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.
YUP, here's one! My CM9 runs perfect with Speer Gold Dot 124 gr. +P Short Barrel. It functions perfectly, and is very accurate in the short tube. The recoil is a bit snappy, but completely controllable.
