I would find somewhere that does consignments. I've sold guns this way with good luck. One shop asked for 10% of the sale price if taking cash, or 0% of taking store credit. Naturally I always wanted more guns so I took store credit and used it accordingly. I noticed guns with proof of accuracy sold much faster and sold much closer or at asking price. I simply ziptied a laminated piece of target with one and it was gone really quick.
