I have a M&P 9c for sale that is one year old. It is in excellent condition. I have three 12 round mags, three full size mags that have only been used once, two bravo concealment single mag holsters, and a galco summer carry holster.
Just wondering what you all think would be a decent price for all of it, or even just the firearm with two 12ers
I would browse gunbroker to see what pistols like yours are selling for. The keyword is selling, not asking price. If you sell the gun face to face I would bundle the accessories with the gun. If you can't get the price you are asking you can always keep the accessories. It's not like you will have a hard time selling anything for a M&P.
