I currently carry a Kimber Warrior with a Surefire X300 in a Safariland 6280 holster on duty. The front strap was checkered 25 lpi by the customm shop and the frame was refinished dark grey for a two tone look.
Off duty I carry a lightly customized Colt Officers model ACP. I'm lucky to work for an agency that allows you to carry what you want - as long as you can qualify with said gun.
I carry a PRO CDP II on duty. Our Dept. also allows choice of carry as long as it is .45. Off duty I have a variety depending on the dress. Generally a Springfield XDm .45. It however is still at the Springfield plant because of the re-call.
