Not as worried yet about the holster as the concealed carry weapon. I love 1911 models but know I'm giving up rounds, love my full size Kimbers and a Dan Wesson. Never felt comfortable with a Glock, and I've owned and sold several. Love Sigs. Like CZ's except for the trigger, Berettas overall, HK overall, S&W wheels, and the list goes on.
Probably going 1911, just don't know how small, or sticking with my Sig 229 for 'small'. Rather shoot the 226 or 220.
There are few bad guns, but I don't 'feel' Glocks.
