CZ-75B Range report; problems!

[freethemouse]

Just took my brand new CZ-75B to the range today. I shot about 120 rounds before today with no problems, but today I shot 200 rounds after cleaning and ran into failure-to-battery problems. All rounds were reloads.

I noticed that every few rounds, and seemingly randomly, the gun would fail to go into battery. The slide would stick out about 1/2 inch, and a slight tap (even a little press with the thumb) would get it back into battery and ready to fire. Also on occasion, the slide would get hung up, then go into battery by itself about a second later (you could feel/hear the slide go into battery after firing; weird).

I'm guessing (or hoping, rather) that I used too much oil after I cleaned it, or that I just need another, heavier recoil spring. I'm not exactly sure what else could be causing this problem.

I'm probably going to order a new 16lbs spring (CZ's springs are supposed to be 14lbs, but my research says it's more like 12lbs) since it's cheap. Hopefully, a better job cleaning/oiling will fix the problem though.

Otherwise, the gun was great. It felt great, it was accurate, and it's helluva lot easier on the hands than a fantastic plastic pistol. I just gotta work out this little failure to battery issue (also, inb4 "you're in your break-in period/this gun sucks period").

UPDATE: Thanks for the advice everybody. I gave the gun a thorough cleaning, including the ejector area. The reloads shot fine, as did various other ammunition. =)

I'm willing to bet it's the reloads.

Did they feel underpowered compared to factory loads? Changing the springs might help, but the root might be the ammo.

If it's underpowered, it may not have enough power to cycle the gun completely.

Good compromise might be to swap springs when using the underpowered ammo. Otherwise, I would just get more powerful reloads or stick with factory. Or better yet, reload your own

Check the measurements of your reloads. I would run them through a chamber checker. This sounds like it is the ammo and not the gun.

What bullet profile. CZ's have some issues with some types of bullet sizes as far as the taper of bullet itself.

[freethemouse]

No, they rounds did not feel underpowered at all. They shot flawlessly on my brother's XD9 (also 200 rounds). But I definitely need to shoot some factory ammo to see how they run.

I'm not all too familiar with the rounds as they're factory reloads (I hope it's not the ammo because it's the cheapest I can get). All I know is that they're 115gr.

Also, if the problem was underpowered rounds, wouldn't my problem be FTE? When the slide stops, the round is almost seated in the chamber, and all the slide needs is a very light push to put it into battery. But I'll try various ammo to see if I still have problems.

I agree on it being a taper issue.......

Remove your barrel and put your rounds in the chamber and see how they fit.

Over oiling doesn't affect this gun. I have an sp-01 and I tend to over oil because it sits in the safe 2 months at a time

I think you may be right about the taper.




The one on the left is is CCI Blazer Brass, and the one on the right is the reload. I don't know if it comes through clearly in those pictures, but the Blazer Brass is longer and narrower.

I'll try some other ammunition and see what happens. Does anyone recommend a cheap, reliable brand?

[Czsp-01-9mm]

I use fed bulk from Walmart, 300 round still no problems, I've used Tula and blazer and wwb to so 600 total over oiled too

[Aspec5vz]

I'll bet it's your ammo. Try firing another couple hundred rounds of a different type of ammo and see what happens.

The reloads are also mixed brass; I'm going to collect the ones that fail to feed to see if there's a common brand that's causing the problems.

Either way, if it is the ammo (from bullet_man911 here on Calguns), it's a total bummer since it is the cheapest I can find. I'd like to shoot a lot and the ammo savings would be substantial (it's pretty substantial even considering the amount I shot today). I suppose I can keep shooting these and just give the slide a tap every now and then.

FWIW, there was about a dozen or so failures to go into battery out of the 200 rounds I shot today.

EDIT: Does anybody have any experience with CZ's and hollowpoints/home defense rounds? Which ones were good and which ones should I stay away from?

Need to do a chamber drop test. Also, pictures so big I cant compare them : )

Mark the bullet with a sharpie, drop in the chamber and see if its hitting the bullet before it fully chambers. I had a issue with the berrys 124grain hollow points, along with a couple of lead bullets that had a shorter, squat profile.



As for HD rounds, both winchester PDX1 and the 124 grain gold dots both work fine in my CZ. They both have a longer, slender profile. The hornady critical defense ammo works decently also, but I havent put a huge amount through yet.

Hey, I resized the pictures; scroll up and see if that's any better.

Also, the reloads I were shooting, at least compared to the CCI Blazer Brass, has "shorter, squat profile" bullets. (Maybe you can tell from the pictures now that they're a bit smaller?)

They sure do look like it, not nearly as bad as the ones I had issues with though. You may want to ask him if he can do some loading for you with the 124 RNHB berrys bullet. A lot of the guys over on CZforums are raving about it.

[pc_load_letter]

I'm going to shoot some bullet_man 9mm reloads through my SP-01 this week. Probably Tuesday. I can report back my results.

I have never had problems with Bullet_mans ammo in my 75bd, or my Ruger SR9 or my P226. His 45's have been great in my SIg 1911 as well.
