About 25 years ago when I was young and stupid I had a Ruger P90 that I started shooting some 45 +P reloads in. At the time this pistol was considered "Overengineered" and "Strongly built". After several trips to the range and a few IPSC matches it started giving me reliablility issues. A close inspection of the reciever showed me something shocking. The front of the magazine well was bent and misshapen just behind the chamber. I'm thankful that this pistol never went "Kaboom" on me but that was the last time I ever played in the red zone on my reloads. The pistol was ruined. Every once in a while God will gently tap you on the shoulder and say "Hey Dumbass, you're fixing to hurt yourself." Whenever this happens you'd better listen because you usually won't get lucky a second time. This was one of those moments and it made me a little wiser.
