Always liked the look of the CZ. I also like that there are cocked and locked offerings. However between the CZ, Sig and Beretta I've always shot the Beretta the best. The Beretta is also a very recognizable pistol.
I really like the Ruger P89 too...
If I could only have one it would probably be the Beretta. Next would honestly be a 3 way tie between the Ruger, CZ, and Sig. I love the trigger on the Ruger in Double and single action, the sig and CZ not as much, but I like the overall feel of the Sig and CZ more than the Ruger.
Again, my vote is for the Beretta... it's a hard thing to say but that's what I say.
