jmbaccolyte Posted July 28, 2012 Share Posted July 28, 2012 (edited) I have a new (2012) M&P in .40 S&W that is putting a sharp crease about halfway up each and every fired case during the ejection process. It's a crease or fold with a definite line in the bottom of the dent (not just a vague dent) and I'm worried about reloading case life. Does anyone have any ideas? I ordered a lighter recoil spring on the off chance... Edited July 28, 2012 by jmbaccolyte Link to comment Share on other sites More sharing options...
Aint No Rest 4 The Wicked Posted July 28, 2012 Share Posted July 28, 2012 I would sent it back to S&W. And I would not reload Just in case. Link to comment Share on other sites More sharing options...
FightFireJay Posted July 30, 2012 Share Posted July 30, 2012 Sounds like either a bad chamber (like the shield that was on here not long ago) or a serious lock up/out of battery issue. Or something else I'm missing completely. Love to see some pics of the brass. Link to comment Share on other sites More sharing options...
