Most of the time I carry my .45 auto.
I sometimes carry my 4 5/8" barrel Ruger SA .44 mag. It's just a tad heavier than the slide pistol, especially when the unfluted cylinder is full of 300 grain XTP's.
Anyone have a Kukuri knife? My brother sent me one, same as military issue, straight from Nepal and I carry it in my truck. You know a pistol can be intimidating but what kind of reaction do you think you'd get from a bad guy when he get's a look at that blade coming at him and the thought of losing an arm or half his head.
