Re: CZ 75 or 92FS
Beretta.
I own several of each.
I have run thousands of rounds through each. 9mm standard, +P, MOSTLY homeloads (milsurp powder, bullseye mostly with 115 gr FMJ).
A used to shoot a LOT with a good friend who shot a CZ-75. By a LOT I mean we'd meet once or twice a month at the range around 9 AM, I'd bring an ammo box with 1,000 rds of home loads and we'd shoot until empty, go to lunch around 2 PM. What he noticed was, on average, about every 1500 rds AND less, the slide release would break. At $35 and change PLUS $9 S&H FROM CZ-USA (there are NO after-market suppliers of this part), this got annoying, so he always kept a spare. He ran through three or four of these. NOT before I bought (three) CZs myself. The more I shot, the more I ran into the same problem.
Being a (less than) amateur gunsmith (mostly 1911 and S&W revolver tune-ups), knowing what I knew about 1911s, I decided to replace the recoil spring on my CZ after the first break and this is what I found out:
STOCK recoil springs on the CZ are 14 lbs. Wolff recommends 13 lbs or higher. The Wolff rep told me the CZ factory springs are really much lower than what they're rated, IIRC ( IF I RECALL CORRECTLY), he told me they were under 11 lbs. The Wolff spring was about 1/2" longer than the stock spring after 1,000 rounds. This is a HUGE difference. When I spoke with the factory rep from CZ-USA he was very matter-of-fact in stating the factory rating for the slide release is ONLY 1,000 rounds. Period. Do they recommend replacing the recoil spring? NO.
This is fucked up (pardon my germanic). TOTAL abgefickt.
I took notes, they're around somewhere, but the bottom line is: expect the slide release to break on the CZ on a regular basis. They're around $50 delivered. If you shoot over 1,000 rounds a year, you'll wish you bought a Beretta. OR install a stiffer spring (talk to the guys at Wolff) and keep your fingers crossed.
My take: CZ for IDPA? Either or. Take your chances. Carry gun? No fucking way. Beretta for either one.
But when I travel, I carry either a SIG P229 in 357 SIG or a Kimber CDP .45 acp. My life may depend on it, and they're smaller.
And there IS a CZ forum. There are several total CZ fanatics who will happily shit all over ANY post critical of CZs. But here's one thread from a few years back:

here's the email chain from me and the factory 'smith:
Glad to be of service.

Thanks again, Mike. Part came yesterday, popped in no fitting required.
I'm looking forward to using it for the next 1,500 rounds - give or
take.

Last but not least, what IS the factory-rated recoil spring weight?
Thanks in advance.

Answers:
1.We stock Wolff recoil springs in several weights (11, 14, 16 &
18lb).
2.The factory only rates the slide stop for 1,500 rds.
3.No need to send back the broken stop. Just give me your address
and I will
send out a replacement.

Subject: Broken slide stop
This is unreal.
I've owned this "made in Czech Republic" pistol for several years
now; it's one of my favorite autos, I probably run 500-1000 rounds a year
through it. Mostly handloads - low pressure, 115gr FMJ around
1125fps, I'm NOT trying to make major, I just do some steel and
bowling pin shoots for fun, not competition.
Today the slide stop broke. Interesting. Friend I was shooting with
has replaced two of these pins over the years I've known him (you've
probably spoken to him, Bill Prudden), maybe 5,000 rounds tops.
I own Beretta's that have at least as many rounds through them, and
1911s with three times that many none of which has ever broken so
much as an extractor.
Thing is, I've been over on the CZ-forum checking around and this
seems to be a pretty common problem.
After speaking with Adam in your parts department a few minutes
ago, I have a few questions:
One - is there a stiffer recoil spring I should be using?
Two - how often should I expect these to break? This might prompt me
to sell my CZs.
Three - Does CZ do quality control on frequently broken parts like
these (metal looks like sintered steel, not tooled) and would you
want the pieces back?
You really ought to take a look at the posts on the CZ Forum
(yuku.com website). I'm sure this is just the tip of the iceberg.
Appreciate your time.
