I have a buddy who is selling his new P-3AT. It has exactly 46 rounds thru it, not more than 2 weeks old. He bought it, now decided he wants a revolver instead. He's also throwing in a 50 rounds of ammo. I was thinking it'd be worth $250 on the top end, but probably end up around $225. He has the dated receipt of when he bought it also. Any suggestions?
