Funny, I thought I had some previous material posted about it here, but I couldn't dig up anything on the search. Perhaps it was lost during a hack-job..
I had the .40 caliber version. I like a lot of what the gun has to offer. Like Walt said, it's got an excellent ergonomic feel, with great natural pointability. It's lighter than a G23, despite its all-steel magazine which was extremely difficult to top-off with rounds 9 and 10. Oh well, a typical CZ mag-loader is included with it.
The porting goes a long way toward taming the .40 in a small, lightweight gun. Feeding and function was 100%, IIRC, and I must have put close to a 1,000rds. throught it.
Now, the trigger is probably thee bone of contention. First of all, it is looooooooooonnnnnnnnnnnng. I can't think of a fair comparison, but George probably came close to describing it.
I was prepared to try and smooth it up, but I couldn't get any assistance with detailed disassembly. Mike at CZ said the factory armorer's manual was all in Czech, and they wouldn't transcribe anything in English for me because of liability reasons. I did not inquire about having Mike do the action work, though I suppose it's possible.
The slide lock is a simple folded piece of sheet metal, and my hand hand an annoying tendency to ride it, no matter how hard I concentrated on my grip. Again, not being able to gut it, I couldn't 'fix' it to suit me.
Somewhere along the line, I decided to do an impromptu reliability test.(
Who knows why...) I placed it in the desert southwest sand and covered it over. I picked it up and fired it through one mag w/o incident. Then, I stepped on it, ground it into the sand, and covered it over a second time. The trigger came to a halt about 3-4 rounds into the next magazine. I hosed it out and cleaned it up nicely. The frame looked like it had been scrubbed lightly with a brash brush, but there wasn't any drastic cosmetic damage.
