A lot of Khar CM9 owners, including myself, shoot Speer 124 gr. Gold Dot +P. The little gun seems to like it and it is a very good performing bullet. YMMV.
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.
no guns = might makes right
