I've got a CZ 75B that is as sweet a pistol as you'll find.
I bought it to shoot production division IPSC. At first, the long DA trigger pull out of the holster put me off. I had a blister on my finger after the first match.
But, now I've put a couple of thousand rounds through it. And it is silky smooth. I no longer even notice the DA first shot in Production division matches.
I've got an XDM 9 that just doesn't seem as comfortable as my CZ. And at first, double taps with the XDM were a nightmare! Although, after spending a few days at the range with the XDM, I'm beginning to get fairly consisten; still not as good as the CZ though.
No way I could be CZ only though. I have a couple of very nice 1911s that are just so much fun to shoot with good quality hand-loads, that I will eventually move to single-stack and shoot the 1911 competitively.
I also want to try a S&W 625 Michulak model. I think it would be cool to try to shoot a revolver in USPSA.
