I'm not a CZ guy, the CZ bug hasn't bitten me, in fact, I only own one CZ, and that's my P-01.
When I decided to switch to appendix carry, I wanted a hammer fired pistol to replace my Glock 19. I researched all of the available options that met my criteria (rock solid reliability, similar in size to the 19, good ergonomics). After looking at/handling/shooting the offerings from FN, Sig, HK, CZ, etc., the P-01 was the clear winner. It's reliable, the same size as a G19, doesn't weigh a ton, and had the rail (I'm in the same boat as you.. don't use it now, but don't want to want it later). Out of the box, the trigger was "meh" at best.. For $50ish, CGWs UltraLight S/D kit (extended firing pin, reduced power firing pin, firing pin block, and hammer springs) made it an excellent trigger for a carry gun.. A bunch more CGW parts just made it incredible.
So with all of the being said, if you want a compact hammer fired carry gun, I don't think there's a better choice than the P-01.
