My main conceal carry gun and the one I have on me the majority of the time is a Glock 36 single stack .45 ACP. It carries very comfortable inside the waistband in front or in the small of the back. It's a pleasure to shoot and has always ate anything I fed it. It's also very accurate and the recoil is mild for a .45. The only other handgun I carry is a Glock 43 9mm when i'm working in the yard or garden and I carry in on my side.
