First off, comments on group size...
I'm happy if I can shoot 4" groups from 10 yards when shooting offhand. Then again, once I've settled into a pistol, I can do it with any of them I've got.
Shooting from a bench, I can usually pull 4"-5" groups at 25 yards, but I'm not a fanbleeptastic pistolero, either. In fact, I'm not even a pistolero, I just like to kill paper...
Also, $319 delivered?! Wow! I thought I did good at $349 plus tax. Oh, well, can't win 'em all. At least I didn't buy the other one I saw at the show for $375...
The great thing about the CZ-75 is that it fits. I have found one person who did not think the CZ-75 fit perfect upon first holding it, but just the one.
