This is from Kahr's web site.Just got back from the gun show. I saw several CW45 but no CM45's. Would rather have the CM just like would rather have a PM9 instead of my CM9 but totally happy with it. So.....I would probably be totally happy with CW45. Dealers there said CM's don't show very often compared to CW'S. K9 comments above I agree with. Sweet.
