Title: New Rami Jamming
Post by: Olmichelson on January 01, 2016, 11:34:12 PM
I just picked up my new Rami about  week ago and immediately went to the local range. Much to my dismay, my first round did not load into the barrel. I ejected it and the second went in. I made a couple of shots and then the same thing happened. The round goes partially in and then jams. If I pull the slide back slightly, the round will usually go in. Out of 100 rounds I would say at least 10 to 15 jammed. I had brought a snake bore along and ran that through a few times when it jammed just to make sure it wasn't dirty, but that did not seem to make any difference. I was using new manufactured FMJ 115gr Lawman and Freedom Munitions ammo. I have not had any problems with either of these rounds before. After I got home I cleaned the gun and tried loading some rounds just to see if the cleaning made any difference. It did not, the round still jammed about 1/3 of the way in. Any ideas?  I have never had any problems like this with my Sigs, Springfields, or Rugers. I really hate to have to send a brand new gun in for warranty work.

Clean it thoroughly, including the magazines.

Try other (hotter) ammunition. Some guns like different bullet profiles until they get some rounds through them. Drop test them in the barrel to make sure they chamber fully.

Do the cheap checks first before the expensive ones.

Thanks for the suggestions. I did clean the gun and both magazines. I am not sure what you mean about using hotter rounds. I guess I am disappointed that the gun had problems right off the bat when I had read how reliable they were. For a carry gun it does make me a little nervous to not have it reliable right out of the box.

I agree and it should be reliable after a good clean and lube. Call CZ and send it back, also it's totally possible the recoil spring is weak. Not having enough force to load a round properly.

First, welcome to the forum.
    Sorry to hear the issues.   Just to clear up, you tore the pistol apart and cleaned all the gunk off?
     You took the mags apart, cleaned and relubed?   
      Sorry, just double checking. I've seen some guys that think cleaning consists of wiping down the outside and running a patch down the barrel[emoji6].

     Another thing to try is that CZ's like to run a little wet. So a good lube is great. Slide rails, trigger bar, sear, etc. They can run pretty dang dirty as long as they are lubed up good.
   As has been said, you can try different ammo also.
   Being that the Rami is smaller, could you be riding the slide a little with your thumb?
      Did you have trouble with both mags?
       If not which one had issues?
    It could just be that the feed ramp needs polished.
    If all else fails then ya, you'll probably have to send back. CZ USA will take care of you.
    And yes, it's a little discouraging having issues with a nee pistol.

CZs usually come from the factory soaked / caked in cosmoline grease, more so than most pistols I've seen -- probably because CZs aren't blued or finished on the inside. All that gunk needs to come out before shooting it.

The best way to get all that gunk out is to field strip it and soak the gun overnight in a bucket of Hoppes #9 (remove the grips or other wood or plastic parts). Also, if it has night sights, make sure the sights don't get submerged in the solvent. The Hoppes will dissolve the grease and use of a bore brush will clear any residual gunk from inside the barrel. Blow dry with compressed air and lubricate.

Also, I don't use bore snakes, since they accumulate grit and gunk that gets dragged through the bore time after time.

Post by: Ruber on January 02, 2016, 12:42:18 PM
Yes, thorough cleaning is key.

Another thing I do with a new gun is pull the grips off, strip it down and clean it, then put it together without the grips and soak it in gun oil or mineral oil and cycle it.  Cycling it while immersed helps lift the gunk away.

Typically then I'll then use an o-ring around the firing pin and dry fire 100 times da and 100 times racking the slide.  I'll clean it off and repeat until the oil is coming away clean.

Not the quickest process, but I don't waste range time on ftf's either... ;)

Try other ammo,  Freedom Munitions ammo is known to have some issues running in CZ's.  They load some of their ammo to long to fully chamber, Cz's have a short chamber.

Thanks for all the great suggestions. When I first picked it up it did look "lubed" up a lot more than my previous handguns. The first time at the range I had not cleaned it, but as I said, I did run a bore snake through it, from the inside of the chamber/barrel to the outside. I could see that I cleaned the loading ramp because it had looked somewhat dirty before I did that. Overall, that cleaning did not appear to make much of a difference. When I did clean the gun, I took it apart, per CZ's instructions and cleaned the barrel, slide, inside and out, and every exposed part I could get to. I then rubbed everything down with a Remington oil cloth (that leaves little, if any excess oil), and lightly put some white gun grease that I had ordered from the NRA on the slides and othe moving parts. Very lightly. After I put it back together it seemed to function as smoothly or better than before I cleaned it. I took both mags apart and cleaned the excess oil from the springs and inside walls of the mags. I loaded the 14 round mag with 14 FMJ 115gr Freedom Munitions new manufactured round nose ammo. The slide stuck in the same place as it did before I cleaned it.  I pulled the slide back not more than a quarter of an inch and the round then loaded. I jacked that round out and the next one jammed just like the first one. Basically, same issue as when I was at the range.  I did that three more times with the same results. At least a 20% fail to load. Although it was the Freedom Munitions ammo, it was their new, not remanufactureed ammo, which has not had any problems in any of my other handguns. Durning my tryout at the range I also used Lawman 115gr FMJ with the same results.  Not sure what else to say. Maybe I got a Monday special. I have sent an email to CZ-USA to let them know about the issue. At this point, everyone's enthusiasm about their CZ's is heartening, but I do have to say that I am a little disillusioned.  Still, I appreciate the help and comments from everyone!

If the gun is clean and smooth but having issues feeding, you could also look at the extractor.  Anything that puts extra tension on the case, debris, burrs, etc.

Personally, I'd take the grease off.  Any extra resistance gets magnified on a gun that small.

Good luck, hope you get it worked out.
Title: Re: New Rami Jamming
Post by: Bossgobbler on January 02, 2016, 09:07:23 PM
Take the barrel out of your gun. 1 hold it with the chamber up. 2 drop a unfired Freedom Munitions round in the chamber. 3 try to turn the round with your fingers. 4 turn barrel upside down and see if the round falls out by it self.
Title: Re: New Rami Jamming
Post by: schmeky on January 02, 2016, 10:01:14 PM
One issue we have seen is the firing pin exit hole in the breech face.  If there is even a tiny ridge at this area, the case rim will catch and cause an angle jam where the round is canted and won't enter the chamber. 

We have fixed a few RAMI's in 2015 that had this issue.  We will take a before and after pic to show what this looks like.  We use a very long carbide drill bit to enter from the muzzle end of the slide (with the barrel removed) to lightly chamfer this hole.  This ensures very reliable feeding.

I then rubbed everything down with a Remington oil cloth (that leaves little, if any excess oil), and lightly put some white gun grease that I had ordered from the NRA on the slides and othe moving parts. Very lightly. 
   This is what I was saying. It's ok to have a little excess oil, CZ's like to be a little wetter than most.
     Depending on outside temps, the white grease could slow the slide down.
   Besides doing the plunk test that Boss described, I would still try to add some drops of oil on the trigger bar next to the frame, couple drops in the sear, and in the slide rails. Not saying anything wrong with the grease, but the new Rami is a tight gun and may need extra lube until it loosens up a bit.
     Did you notice if your issue happened with both mags?
    Stick with us, I know it can be frustrating. Just keep in mind, every manufacturer out there may have an issue with a brand new gun. CZ USA will take care of you[emoji6]
 
Schmeky, that's interesting. It would be nice to see pics.

Agreed ^^^^

I would like to see what you are talking about David.

Do you do that on all RAMI's?
Title: Re: New Rami Jamming
Post by: schmeky on January 03, 2016, 02:10:34 PM
First pic shows the firing pin breech exit hole as delivered from the factory.  Note the hole is not concentric, which is unfortunately pretty common.  In rare cases, there is ridge or lip of metal that can dig into the case rim and cause a jam.
(http://imagizer.imageshack.us/v2/640x480q90/633/Lb3wNr.jpg)
So we chamfer this hole per the attached pic.  We began doing this as standard procedure in 2015, so we can catch that 1 in 2,000 (or so)!  This ensures the case rim will not have anything to dig into and contributes to smoother feeding.

Post by: Olmichelson on January 03, 2016, 05:22:45 PM
Interesting ideas and photos. The white gun grease I used is so fine and I put it on so light that a person can hardly see it. The temperature is not a problem that I can see. I put one round of the Lawman ammo and one of the Freedom Munitions into the separated barrel, with no issues with either round. Both went in with no trouble and I could finger spin both. Both dropped out with no problem. The inside mechanics do not look exactly like the pictures posted by Schmeky.  It looks like my firing pin hole is round.  However, I do see that the face of mine is smooth from the bottom to the top of the slide and in the Schmeky's pictures there is a ridge that protrudes from the top of the slide.  I have pictures, but it does not look like there is any easy way of posting them without putting them out on some photo site. Maybe I am missing something. I see that CZ USA is on holiday break until tomorrow and I have already sent them an email letting them know I have a problem with my Remi. Thanks for the suggestions.

Post by: Ruber on January 04, 2016, 09:34:11 AM
Thanks Schmeky!

Olmichelson,

I'm a big fan of clean, lube, shoot, repeat.  I can't tell how many times you've had it at the range or how many rounds you have through it after cleaning and lubing it.  But as mentioned, these like to run wet for break in.  If I were to not tear it down for a thorough cleaning, I'd take it to the range dripping oil (no grease), shoot 50 rounds, field strip it, wipe it down, drench it with oil and repeat.  I'd do that for about 4-500 rounds before I'd start to get worried.

The cool things about the CZ's are their durability, accuracy, and value.  My CZ's hold up much better than my Sigs or S&W's and are more accurate across a wider range of ammo.

But the cheaper models can come a little dirtier, a little less fitting, needing of more break-in time.

My custom shop Sig showed up perfectly cleaned, tuned, and lubed.  But it also cost four times what my RAMI did. Some of the higher priced CZ's are pretty slick right out of the box, but you pay for it.

Kinda a long winded way of saying don't judge the gun on the first couple range sessions.

All that said, some do slip through with machining problems like Schmeky pointed out.  I've also seen defects in/around/opposite the extractor cause feeding problems too.

CZ USA should get you going right pretty quick if you choose that route too.

Run it wet, wet enough that you get some oil spray on your shooting glasses. Wet means wet, don't split hairs.
Run at least 400 rounds through it in one session. Shoot it in (break-in) as the recoil spring is new, metal surfaces have not mated and smoothed.
Run it using ammo with some zip to it. Try Remington Golden Sabre for feeding JHP, this ammo has a very forgiving bullet ogive and seems to feed in every gun I have ever used it in.
Keep the magazines fully loaded for a few days. A stiff mag spring can create friction. Try downloading the mag one round to ease feeding during break-in.

For what it is worth - even my Shadow Tac II Custom exhibited some break-in issues similar to yours as did a Nighthawk Enforcer. Stick with it and try above suggestions. Good luck with that awesome gun!

If you are still having the problem, take a look at a post of mine late last year on here.  When I got my Rami, it would jam with the round only partially chambered at least once per magazine load.  I looked at all of the suggestions on the forum, and I tried most of them with only partial success.
Close inspection showed the round was sticking at the extractor, which was very stiff.  A really good cleaning of the extractor pivot point with a little kerosene, working the extractor to and fro against its return spring with a small soft brass bar to remove the thick grease that was making it stick, then lubing it with a little light gun oil made it move much more freely. Suddenly, I  could reliably cycle some brass snap-caps that also used to jam. The problem was instantly gone, and it's now gone well over 1500 rounds since then without a single malfunction.

Title: Re: New Rami Jamming
Post by: akspotmom on March 15, 2016, 02:00:15 PM
I had read this post (actually EVERY post) before I bought my RAMI D and when I got a few weeks ago it I took it apart to clean out the grease everyone talked about there was none. Just some light oil and not a lot of it. I wiped a little off the outside of the gun and proceeded to shoot and discovered the joy of this pistol everyone talked me into buying!

Since then I have had about 200 rounds or more through it of several brands, RN & HP, as well as home rolled with various grains of powder testing lighter loads, both the 10 and 14 round mags, and not a single jam and only 2 FTF on home rolled, but fired on the second strike (the reason I love guns you don't have to rack the slide to get a second opinion and throw precious ammo on the ground). The FTF were both from the same batch, so unknown what the issue was, it didn't happen again, but sure looked like a light strike.

Mine shows a mfg date of August 2015.

So in my limited experience (with this gun anyway) I would say that if there continues to be feeding issues with the gun in question I would send it back for a replacement or some work. For the price it just doesn't seem right that it would not be good right out of the box.
****************************************
Update August 2017:

Since I got this gun last year I have been shooting it a lot, around 100 rounds a week, sometimes more, sometimes less. I have between 5000-6000 rounds through it now and it runs perfect. I have changed the large recoil spring 2x, but not sure it really needed it. They were definitely shorter than the new ones, but I wasn't having any issues. It gets cleaned after every range session and kept very well oiled. I have used various factory loads with no problems (other than some are more accurate in it than others), but mostly use hand loads. At Front Site I shot 300+ rounds of Hornadys in one day and only gave it a squirt of oil half way through the day just to be sure, I wasn't having any issues at the time.

If you are using reloads, the plunk test is important, once the size it can take is worked out there will be no issues there.
I have found that the early FTF have turned out to be using primers from the 50's, other issues from old powder. Using up old components, I mean REALLY, REALLY old, has caused us issues in every gun we own so we quit some of the older stuff.

Like to get some opinions.  I have been reading alot of threads in regards to cz jams and I'm not sure what else to do?

I recently purchased a brand new RAMI BD 9mm. Love the gun but i am getting too many jams.  I ran aluminum cased ammo without any problem BUT I'm having issues with brass cased ammo.  I average 2 to 3 jams per 50 rounds.  Probably had 400 rounds through the gun.  I field stripped the gun, cleaned and oiled it (including the extractor-removed, cleaned and oiled) and still the same issue.  I have used A-zoom snap caps as well and everyone jams, they don't load correctly and sometimes its extremely difficult to eject the cap (can't rack the slide its so stuck).  I have used 4 different magazines, the two that came with the gun and the two from my sp-01 (i have never had issues with the sp-01 mags used with my sp-01), and I get jams in the RAMI with all of them.  Any suggestions and should i be concerned that the gun may need serviced?  thanks for your time.

Welcome.
   Have you tried the plunk test?
   Is the brass ammo factory or reloads?
   Have you polished the feed ramp?
     Are your mags clean?
Strange that snap caps jam. Are the jams the same, with all ammo, i.e. stuck slide?
   It may be that your pistol has to go back to CZ.

thanks for the response.  I did not try the plunk test and the rounds are new.  i was having issues with magtech rounds but lawman worked well.   mags are clean and yes i polished all the internals i could get to including the feed ramp.  as an update, after this i put 200 rounds of the magtech through the gun and it was beautiful, no jams!!!!  thanks for the advice!!!  i am still scared to try the snap caps.

Great thread as I am having the same problems with my new RAMI. I'll try all of your suggestions on mine.


An update to my problems and what seemed to fix them:
1.Field strip it, remove the grips and go at it with gun scrubber or brake cleaner. Don't stop
until the excess scrubber runs clean. Let it dry completely. then over lube with a quality gun oil.
Then I used compressed air to blow the excess oil off. When putting it back together an extra drop
or two on the rails and other high stress points. The feed ramp on mine was already highly polished.

2. The magazine springs turned out to be the weak points on mine. The 10 round now has a
Woolf 5% extra power spring for a CZ Compact/P-01.
The 14 round magazines now have Woolf 10% extra power springs for a full size CZ 75B.
Yes they fit and you can still load 14 rounds. :>)

The deep cleaning and extra lube during brake in and the above springs have fixed mine.
It now has 1300 rounds thru it, with the last 1000 being 100%.

It's really a neat little pistol.

Post by: bmrshoot on April 12, 2016, 09:19:58 AM
everyone has been suggesting issues with the gun, nobody has suggested his form. #1 cause of feeding issues in compact/sub compacts is the shooters form. ( regardless of how many other pistols or tens of thousands of rounds you have fired before with no issue). Chances are, there is nothing wrong with that pistol. Have a few friends shoot it or a few random people at the range and see if the issue still exists.
Title: Re: New Rami Jamming
Post by: cntrydawwwg on April 12, 2016, 12:15:10 PM
Welcome bmrshoot.
    Your correct that shooting form did get overlooked. Roughly 8 out of 10 times, the issue with a new CZ (especially a Rami) seems to come down to cleaning and lubing. So speaking for my self, I've become complacent in concentrating on only that issue first.
Title: Re: New Rami Jamming
Post by: Rainsong on April 12, 2016, 01:53:48 PM
Hmmm.   I just ordered a RAMI and use Freedommunitons 115gr almost esxclusively for practice ammo.  I hope there isn't a problem.  It cycles fine in my CZ75 and Shield.

Post by: Starlet4ag on April 12, 2016, 01:54:35 PM
I had these problems with my Rami bd also. After searching the net i found out using kimber springs made for a compact 45 would fix the problem. Here is the model number?18lb Wolff for Kimber Ultra Carry part#51818?. These fixed the problem in my gun. If anyone is having similar issues i would try this first. I was starting to doubt the rami but now its been reliable and accurate so i have no complaints.

Thanks for the welcome. I just got my RAMI yesterday but have had my Accu Shadow for over a year now. I know in the Shadow I use an undersize die just to ensure no hang ups but it cycles factory loads just fine. I haven't shot the RAMI yet. I just know that customers are always bringing me G42s, G19s, PPKs and other smaller 9mm/380s complaining of feeding and stove pipe issues. I have them sign up for my club presidents class and usually that fixes the problem without any mods to the gun. Figured it was worth a shot. I'm going to take everyone's advice and make sure I clean the RAMI out really good before I take it out since it's a factory gun. I didn't have to worry about the Shadow because Angus did his magic on it and the customer I sold it to had it for a month before I bought it back so he had about 1200 rounds through it already. It was well broken in.

FWIW guys, I've been lucky I guess. Probably 500-700 rounds thru my BD and zero issues that had anything to do with the pistol.
    Once was when I didn't have my CGW disco fit quite right, and once with some ammo that was too long  (all my fault, not the Rami's)
    Heck, I still have the original outer recoil spring in, and some have had to replace at 500 rounds. ( since it's my carry, I do have a new one in other than range. Better safe than sorry[emoji6])
    I'm far from teaching anyone, I just followed the advice I've found on here.

I picked up a new RAMI decocker in 9mm about six or seven weeks ago. From the beginning, I'd been having anywhere from zero to three failures per box of ammo, where the slide would not go into battery, by approximately a half-inch or so. Most of the time the tap from a failure drill would be enough to pop the slide forward into full battery. I went through a lot of the suggestions in this and other jamming threads: full cleaning, different mags, exercising the extractor spring, polishing some of the friction areas, running it dry, running it wet, et cetera. Nothing seemed to fully cure it. Last week I went ahead and ordered the 18# Wolff springs. With a bit of cursing and some bruised thumbs I managed to get them installed properly (note bene: I'd suggest grabbing a helper for another set of hands when trying to get the retaining plate off and on). Since then I've run about 150 rounds through it, without a failure of any kind.

I picked up the RAMI with the intention of it being my carry gun, but I haven't felt comfortable with the number of failures I've been experiencing. I'm tentatively hopeful that the 18# springs have gotten me sorted out, tho. I have a lesson scheduled this Thursday so I should be putting another 150-200 rounds through it. I'll report back then.

What brand of ammo are you shooting?  The reason I ask is that there seems to be a lot of poorly manufactured stuff being sold cheap these days - you couldn't give me Winchester White Box, Perfecta, Tul, etc.  I'd rather pay a dollar or two more for something I know is reliable than risk FTE/FTB every 10 shots.  I recently purchased some .45 ACP WWB and the bullets were seated so loosely in the cases you could move them with your finger.

What brand of ammo are you shooting?  The reason I ask is that there seems to be a lot of poorly manufactured stuff being sold cheap these days - you couldn't give me Winchester White Box, Perfecta, Tul, etc.  I'd rather pay a dollar or two more for something I know is reliable than risk FTE/FTB every 10 shots.  I recently purchased some .45 ACP WWB and the bullets were seated so loosely in the cases you could move them with your finger.

My indoor range requires you to run only what you purchase from them, so I've been limited in what I could try out there. Was a few of Fiocchi 115 varieties, and Blazer brass cased 115. The ammo wasn't particularly bad, as I've run a ton of it through both my full size 75, and a Glock 43 without issue.

I'm tentatively hopeful that the 18# springs have gotten me sorted out, tho. I have a lesson scheduled this Thursday so I should be putting another 150-200 rounds through it. I'll report back then.

Had a lesson yesterday, and ran another 150+ rounds through without a hiccup. So I'm sitting at 300+ rounds with zero failures. I've intentionally left the gun dirty through all those rounds, as well. I'm going to try and run it without cleaning until I either get a failure, or hit 500 rounds. I figure if we make it there I can start feeling comfortable with the reliability.

Good luck getting a failure. :)  My RAMI has about 400-500 rounds through now, mostly Fiocchi 135g FMJ (bulk), some Fiocchi 147g JHP, and Hornady Critical Defense (135g JHP, my defensive load). I may have also have run some S&B and American Eagle (first time on the range, wanted to try different ammo, but had two new guns and lost focus). Had not had a single failure other than the over-travel screw of the 86c trigger walking out after about 200 rounds and preventing firing (it's loc-tighted now). In fact, I don't recall any failure at all with the 75, RAMI, PCR or Scorpion. Oh, I take that back, there was ONE primer that didn't fire even after second and third strike.

If the over-travel screw stays put next time at the range, I certainly trust my life to the RAMI. (If the screw walks again, I'll either leave it, since it only happens after 200 rounds, and I don't expect to shoot that much in a self-defense situation, or it gets removed).

Just an update: I hit 500 rounds at the range today, since replacing the stock recoil springs with the Wolff #18 set. No failures of any kind since putting them in. That's with zero cleaning. Not even a wipedown. And maybe its just confirmation bias, but I really feel like I'm making better followup shots with the stiffer springs in place.

I'm just now starting to feel like the RAMI might be the mini-75 that I want it to be :)

Glad to hear it went well! I think the follow-up shots make sense. The stiffer spring tames more of the slide recoiling, with less impact at the end of the slide travel, resulting in less muzzle rise.

That's why I don't understand why folks immediately put weaker springs in their guns. Yeah, it's easier to rack, but the slide is tamed less, resulting in more slide impact, more slide stop pin abuse, more muzzle climb. The previous owner of my PCR had installed a SS guide rod and weaker recoil spring. Was easy to rack, sure. But I immediately put the plastic guide rod back in (so the SS one doesn't damage the alu frame) and stock recoil spring. Harder to rack, sure. But it's a pleasure to shoot. I'm more accurate with the PCR over the RAMI or full-size 75, likely just how it fits my hand.

Anyway, glad your RAMI is running well! And yes, she's surprisingly accurate for a small pistol!   :)


/me removes RAMI from holster, gives her a kiss, and reholsters her.

My first RAMI jammed at least once each magazine. Before I ran across this thread, I had tried all of the cures that are mentioned here to no avail. I sold it. After finding the thread and seeing what Schmeky has done to make sure the ones he sells don't jam, I bought another one from him, plus a P-01. Both pistols are having the pro package installed along with F/O front sights and adjustable rears. He is going to work his magic on the breech face and the firing pin exit hole, on the RAMI. I called last week and was told my pistols would be on the worktable this week. CZ's are amazing pistols! I want this one to work.

After about 800 rounds through my Rami BD I started getting regular jams.  The slide doesn't quite complete its cycle, by maybe a half inch or so.  A tap to the back of it and it was ready to fire.  I knew cleaning wasn't the issue.  Thought it was either a weak wrist or the spring issue discussed here.  I ordered the 18# springs.  Two of us working on it could not get the retaining plate off, no matter what we tried.  I had specfic directions from this site and it wouldn't budge.  So I just replaced the larger spring and headed for the range.  Problem solved!  200 rounds without a single hang up, right or left handed.  So happy I found the answer on this forum.  Thanks everyone!
