by Wolverines!!!!
It is impossible to have too many of these. Even if you had a giant vault full of them and you swam through them like Scrooge McDuck every morning... you could still use a few more.EFM

by Barack Hussein Obama
What else is there to say, service is the absolute tops from PA and the mag is pretty nice too. The only thing I would ding PA is the 1 mag limit right now, wish it was two mags.
