Carbon buildup

[1SOW]

Just some possibilities:
carbon/crud behind the extractor claw and/or in the channel.  Clean thoroughly .. don't lube
Friction on the slide rails ...lube. Check for free slide travel with the recoil springs out.
Weak mag spring or dirty mag/follower causing it to be harder to feed the top round.
Lube the bbl bushing with light oil or equivalent.

With your pistol carboned up and After the above,  in a safe location, finger away from the trigger,   feed a mag full manually pulling the slide all the way to the rear and release (same as firing does).  If no FTF,  then feed a mag full by manually jacking the slide to lock back and releasing the slide with the slide stop.  (Gives only partial feed force from the recoil spring). It should feed.

Sounds like a weak recoil spring. But have you considered polishing the feed ramp?

Replaced the spring; polished the ramp.

What ammo are you using (brand, grain, etc.)?  Does it consistently fail regardless of ammo?  Also ... the RAMI can be a bit snappy if you don't carry out your fundamentals (like grip).  Have you noticed more snap during the times it fails?

I've run at least six different brands of ammo through it and didn't see a pattern.  When I first got the Rami I did have a few FTFs because of recoil, but I figured that out.  I did put a Wolff 18# outer recoil spring in it and didn't have a single FTF in 200 rounds, but the recoil with that spring literally sprained my hand and wrist after 200 rounds.  Hurt for 4 days!  Took that out and replaced it with a new factory spring. 

I just don't think I should have to be working this hard to keep firing the gun.  I'm a newbie, not a gunsmith.  I can't keep tinkering with it every time I want to use it.

I had the same problems with a Ruger LC380. Constant FTF no matter what I did to it. I even sent it to Ruger for "repair", they fixed nothing. Couldn't trust the gun so I sold it.

That's discouraging.

I'm quoting Shmecky from a previous thread:

Most likely you will need to:

1) radius the firing pin hole in the slide breech face
2) chamber may need to be reamed with a finish reamer
3) mirror polish the "break over" ramp on the barrel

We have seen this several times with RAMI's.  The above has fixed them every time (at least so far).

In addition, I have found the bottom edge of the breach face sometimes needs cleaning up.

These issues can add drag that can cause the slide to hang up if the springs get weak.

I touched briefly on this earlier but have not seen if you inspected those areas or if you have any photos of the breach face, etc.  Sorry if you did check all that, I don't mean to sound like a broken record...

Ruber:  I mostly don't know what all that is exactly and don't have tools to "radius" or "ream" or "mirror polish".  I'm hoping CZ does what needs to be done.  Otherwise, I will have to take it to a local gunsmith.

Hey, sorry kkborre, I know you've been posting for a while, didn't know if you were following any of Schmeky's work.  There were some good photos posted a while back, and of course, I can't find them now...  I'll look some more when I'm on a real computer.

Even if you don't do the work yourself, it's good to learn where some common rough spots and available solutions are.

I really believe the gun should be reliable under different circumstances, with fresh or old springs.  I had mentioned in another thread how i use reduced loads in mine with new/young shooters and it still cycles.

Hope to get some pics up for you shortly...

I think I did see the photos you are thinking of when I was cruising the forum threads looking for a solution to my FTF problem.  Changing a spring is one thing, reaming and such is something else entirely!!

I too would consider polishing the feed ramp.

I'm still having FTF issues with my Rami.  I'd say about 10% are sticking. The last trip to the range I was cleaning the ramp after about 100 rounds to try and stop the FTFs.   The new outer recoil spring has about 400 rounds on it.  The slide just barely doesn't make it into full battery; a tap on the back is all it takes.  But I shouldn't have to stop to tap the slide; especially on a EDC.  I emailed CZ and they sent a warranty repair label.  I hope they can solve the problem, and it doesn't take months!

Got an email from CZ today that they are finished with my Rami and I will have it back soon.  Super fast turn around; one week!  Here are their comments:  "Adjusted feed ramp, extractor, slide stop, breech face lead in and firing pin hole."  Not sure what all that means exactly, but I hope it solves the problem. I can't wait to get it back.

[Ruber]

Awesome!  That should do it, and covers much of what was mentioned in this and other RAMI ftf threads.

I wouldn't say CZ has the Monday Morning guns some other big companies have had, but of the seven CZ's I havre, one very clearly did not get the level of finishing touches the others received.

That's good to hear.  I haven't even been carrying it every day and I still miss it!  I hope it's back this week so I can take it to the range Sat.

yeah I wonder what they meant by adjusting the feed ramp.

RANGE REPORT:  Yahooo!!  225 rounds and not a single FTF!  The very first shot I immediately noticed that the gun felt different.  Before I sent it in for repair I would have had at least 10 FTFs out of 225 rounds.  Whatever CZ did to it, it worked!  I am so pleased!!
