Are you sure you even got your original pistol back?
Dude...I have to give you some props! From every post that you have made here about this lousy situation...you have shown marked restraint and positive attitude.
If I had any M9 parts I'd be offering to help...most I can offer is best wishes. It'd be a real shame if at the next game this guy caught a CO2 powered 40mm rubber slug in the nuts from close range...(I was messing around with one and they pack a real whallop on propane).
