I don't know, I got a great deal on a Winchester 1300 at a pawn shop. $100 less than the gunshop, and mine is in much better shape and it came with a case. The two places are several blocks from each other on the same street.
That said, most of the time pawn shops are too high, but most are willing to make a deal with you. The one I bought my 1300 from wouldn't budge at all, (and trust me, I tried, several times). They wouldn't move at all, no matter what. I actually asked the girl, "What kind of pawn shop are you?" "Not a good one," she answered, then paused, "At least, not for bargaining." She slipped that last part in at the last moment.
I still got a good deal on it though, but it was the strangest pawn shop I've ever been in.
So yeah, make them an offer, or ask them what they can do for you, then make them a lower offer. That's what pawn shops do. Well, most of them anyway.
