I've run about 1500 rounds through my M&P40, and now it will not keep a mag in the damn thing. I read that in the US there have been similar issues repaired by a new hardening process on the mag retention pin.
Any experiences hereabouts? I have never sent a firearm to the US for repairs; is this a challenge?
Thanks
