Just shooting paper at range when BOOM It was a hot load ,I know. I reload .45acp for 2 guns. If it was a double load then it had no more than 9 grns of Unique. I load light for target. This is a plastic handle. It blew back in my hand, powder all over hands and face. I've had a lot of low loads and know ALWAYS to check barrel for slug. I'm positive it wasn't a slug in barrel. This cracked the plastic on magazine from top of trigger on 1 side all the way around to the other. The mechanics of the gun are fine. Just when you pull it back the dovetail and hammer just droop. Question?? have had this for about 1.5yrs. How good is Kimbers rep and think they may fix it.??? Long shot I know, but I'm open for suggestions on this
