Picked this up this morning at the gun library. Funny thing, I was at a pawn shop yesterday morning and passed on a pretty decent P220 marked W. Germany because they had "too much in the gun" so "couldn't" come down on the price. Just gun and one mag. Then saw this today, with original grey SIGARMS case and extra mag and manual for $50 less. I don't think the extra mag has been out of the wrapper, and the gun looks like it maybe had a mag or two put through it. Some handling marks on the slide but nary a mark on the frame or grips. Barely any wear on barrel or slide rails. Circa 1996 based on serial number and peened "W." All in all I'm satisfied.
p.s. Not having the German proof marks, I would imagine that this is a U.S. assembled gun from German parts. Still pretty neat.
