I have an M&P 9mm (full size) that I have been thinking about trading or selling for a while now. I bought it (new) about 2 years ago, and while it is a great shooter, I find it sits in the safe more often than not. The problem is, I'm not really sure what a realistic price/trade value would be. I bought the range/carry kit that includes the gun, 3 magazines, Blade-Tech holster, and mag carrier, so all of that would be included (not that the holster and mag carrier are really worth all that much). The pistol has no signs of wear, and is overall in excellent (like new) condition. Also, I had Trijicon HDs installed when I bought it. Any ideas as to what I should be asking for it?
