I sort of "happened" into my CM9. Won the silent auction bid for it at an NRA fundraiser. But I will say not only did I happen into it, I am very happy with it. If I were shopping for one I would choose the CM over the PM. Dovetail front sight, and polygonal rifling to me are not worth the extra cost for a small CCW pistol. It shoots just fine as is!
