Title: Disappointing Day at Range
Post by: dsierra on January 09, 2019, 03:24:52 PM
Pretty disappointed.  Was all fired up about shooting the RAMI for the first time.  Went through three magazines and was barely hitting the target...groups were left and low.  I was really freaking out.  Have never shot that poorly.   Then, I noticed it.  The rear sight had become loose and shifted left.  I borrowed an allen and snugged it up but only had a little ammo left except for that in my Hi Power mags.  I got off 4 or 5 rounds and the sight loosened again.  Disgusted and not wanting to borrow the allen again, I gave up. 

Better luck next time...I hope.


Meanwhile, as usual, I was dead on with the HI Power.

Don't get discouraged. It happened to me too,
Always have an Allan wrench with you. Set the rear sight to your liking. Tighten it. Go home, Mark your rear sight position, take the set screw out and put some blue locktite on the screw and retightnen. It should not come loose again

mecenas, thanks for the encouragement.  I was sorta depressed.  Never crossed my mind that sight might come loose.  Will definitely have Allen wrench in bag from now on and will go the loctite route this evening or tomorrow.  The few shots I got off after tightening were dead on with sight in factory (detent) position.  So, I'll start from there.  Thanks again for the encouragement.

Probably be a week before I get back to the range.  Will provide update when I do.

Lock-tight the sight setscrew.  Also, check the grip screws regularly, and/or buy some extras.  (don't lock-tight)  Ask me how I know this  (After teething, Rami shoots great and is 100% reliable.

The outer dimensions of the screw sleeves on the RAMI are more oval like with slight corners than circular. Make sure they line up with and sort of fit into the similar shaped hole in the grip so they don?t shift or loosen while firing. I place a finger on the sleeve from inside the mag well to hold the sleeve in place while tightening the screw.

 My rear sight did the same thing I ended up removing the sight and drilling it and taped for it for a larger dia. set screw it's now locked in place.

Can you determine if the slide dovetail or the rear sight is out of spec?

No.  I guess I could take it to a gunsmith and have the dimensions checked.  For now, I?ll ASSume that they are OK and loctite the set screw.  Any further trouble and I will investigate further.  The few rounds that I did get off between tightening the sight seemed to indicate proper alignment.

Took a 2nd look at the rear sight and it moves freely with the set screw loosened.  I mean no resistance at all really.  Just slides right off the slide and goes back on with little effort.  Should it fit that loosely in the dovetail?

No, there should be significant resistance that would require a sight pusher tool or tapping with a hammer and dowel to move the sight. The set screw is just there for extra security. I would send the pistol back to CZ for repairs or replacement of out of spec parts.

My rear sight also moves, although it does not look like it is loose. I have a CZ Custom rear sight - not the true OEM sight, so it means that it is designed that way. I think that putting locktite on the set screw and, in addition to the left and right side of the sight itself will fix the problem. Once the set screw is set with the locktite, it should never come out by itself, and if it is tighten, there should be no movement of the sight at all.
I would do nothing else for now. Just enjoy the gun and remember always check the sights before any shooting - I do that with all firearms I have. It solves that very unpleasant feeling when you shoot and the target is completely blank.........

OK MeatAxe thanks for the advice.   I  contacted CZ-USA and the rep said that the sight needed to be friction tight and that I should send it in.  I filled out the Warranty Request form.  What happens next?  Will I send just the gun or the case and all? 

Thinking about it, if the dovetail was milled too large, then I would think the gun would have to be replaced as I can't see how that can be repaired.

Well, just got a FedEx mailing lab to return just the slide.  Guess, I'll send the entire slide assembly since they didn't specify.  In any event, CZ rep confirmed that the rear sight should be friction fitted rather than loose as a goose in the dovetail and they sent return label promptly.  Can't imagine how they can remedy the over milled dovetail but then again, I know little about that sort of thing.  Will update when there's progress to report.

 My guess is that your dovetail is fine and the rear sight base is undersize no big deal most of the time they are over size and must be driven in place.
Title: Re: Disappointing Day at Range
Post by: mecenas on January 12, 2019, 02:08:40 PM
At worst, they will replace the slide. No one at the factory is going to fool around with the dovetail alone. No time for that. It is simpler to replace the slide and since it does not have a serial number it does not have to go through registration at FFL
Title: Re: Disappointing Day at Range
Post by: dsierra on January 12, 2019, 02:23:52 PM
Well, if they replace the slide, I will have a mismatched gun as there is a serial number on the slide.  Not a great outcome, considering that I bought the gun 9 days ago.  If given an option, I would rather have the old slide back or a replacement gun.  Guess, I?m at the mercy of CZ USA.

I hope you're guess is right.  That would be a simple solution.  I appreciate your input, but it is a kinda a big deal when the rear sight falls off the gun while shooting. It moved almost completely out of the dovetail.   As stated previously,  I tightened the set screw and the sight moved again after 4 rounds.  QC missed this one.

Most likely the rear sight is out of spec, especially if it?s a Meprolite night sight, which are made of soft, crappy metal. If it?s the slide dovetail out of spec, they can probably weld some more material in there to tighten things up.

They will replace the slide if the slide is out of spec. More time would be involved in welding/machining and refinishing than just replacing the entire unit. If the slide is out of spec CZ-USA will likely have him send in the frame as well and they will just replace the entire pistol so all # numbers match.

I am sorry, my bad. Obviously I said something without even looking. There is a serial number on the slide and that would cause a problem if the slide needed to be replaced. I do not know if the CZ factory has slides without serial number as it is not required by the US law. The only valid, true serial number must be on the frame - the other locations can, but do not have to, have a "duplicate" number. This year I am planning on visiting CZ factory in Uherski Brod - I will ask that question.

Under the circumstances, fixing the slide would be a valid solution to the problem. I am sure CZ will be up to task.

Good luck

 Don't worry CZ will handle it and you will have your new pistol back in a few days most likely with a new rear sight.  A lot of people don't like CZ's choice of night sights your problem is common  I like mine now that they stay put and don't move around.  My night sights went dead when my pistol was just a few days old so I sent the slide back to CZ and I had it back in 6 days. That is when my rear sight started moving around I didn't want to be without it for another week so I fixed it my self. I also added the CGW extended firing pin and a few lighter springs it now has many thousands of rounds fired and runs like a top I love it.

Well, CZ has my slide.  Got this email today:

Return Authorization has been received by CZ-USA.

Item: 91754 - CZ 2075 RAMI BD, 9MM, BLACK AL

Serial Number: C66

 

Typical turnaround time is 4-6 weeks. Please allow us this time to concentrate on your firearm. You will continue to receive a weekly status update email until your case is complete.

Surely, CZ will rectify the situation quickly.

Well, took the RAMI to the range today and the rear sight didn?t fall off.  I must admit I was pleasantly surprised at how accurate the little guy is.  Didn?t like the 10 round magazine at all.  The 14 was ok but the 15 round 75 Compact magazines were my preference.  All in all, I?m satisfied with the RAMI and look forward to shooting it again.

Thank you for keeping us updated. I was wondering what is particularly nicer, or more comfortable,  or perhaps more reliable in 15 rd  CZ Compact vis a vis 14 rd Rami mag ?

Did you install any kind of a magazine sleeve to cover the extension of CZ Compact ?

Try full power defense loads if you?re not already. The RAMI shoots mouse fart loads low and left.

No, I just used the regular 15 round magazines.
