wow bum deal man, i just took mine out and ran three mags through it this morning. Had some feeding issues but I think that it was more of a breaking in/loading issue with the spring in the magazine than anything else.
I gotta say though I love my PMR. It was a great find and a so far seems like a excellent weapon. I mean 30 round mag with some hollow points? Can't ask for more then that.
Hope your new pin works out man!
