Reloaded 100 with 1.158 over all length, used three mags, not one problem. Am learning to shoot more accurately, got a long way to go.......groan. Got my CM45 today, need a few parts for the Dillon square deal before I can reload .45 acp, hope the CM45 works as well as my CM9 which has never failed me! Anyone have bullet weight and other reloading suggestion? Read somewhere that small semi autos work best with slightly hotter than average loads. Anyone have trouble with lighter loads with the CM45? Every time I shoot my CM9 I like it even better. What a great gun!
