I sometimes carry my Kahr CM9 in my front pants pocket. Fits fine in most and it's not too heavy in regular pants. It does tend to drag down shorts with an elastic waistband.
Jim's Rules of Carry: 1. Any gun is better than no gun. 2. A gun that is reliable is better than a gun that is not. 3. A hole in the right place is better than a hole in the wrong place. 4. A bigger hole is a better hole.
