Personally, I hate the Beretta, I've seen too many issues with them. Yes I know, keep it clean, change the springs every x number of rounds, blah, blah. Forget it, won't own one. Now the Taurus PT-99 (which I owned) is ok, I bought it off a friend with upteen bazillion rounds shout through it and Taurus took it back and made it like new (I suspect they might have de-milled the original and issued a new one with the same serial number, but that is just supposition on my part). I liked it and shot it a bunch, but I traded it off long ago for something else. It was good but too bulky for me.
The CZ-75 is the shizzel (to use the vernacular), that is one of the best feeling weapons I have ever picked up. Sights falling effortlessly on target, bullets with the disturbing tendency to fall in the same hole (no, I don't think it's me I'm not that good), and CHEAP! (comparatively). The guys over at CZ forum like to swap out the factory springs for wolff (use the BHP recoil spring though, the CZ spring is actually for a Witness and is a bit bigger than required, most say #15 or #16). You can get a CZ-85 smooth trigger and spring replacement from this guy;

If you do want the CZ, get it, and get an AK with the change. Best of both worlds, new pistol and a rifle you can play with all day on the cheap.
