Call Springfield and tell'em what happened. They'll have a new pin on the way in a day or two. If it doesn't press fit, stake it and do the slidestop swing test.
I'll let my brother do it.
It is his gun after all.
Besides, his owning 3 M1As of recent manufacture and a SAR-8 has practically gotten him on a 1st name basis with their customer service reps.
I was just going to see if I could figure out if that was normal and if not, could there be something else wrong.
Thanks for the help!
