I have Mossberg 590 20" barrel with the extended tube (8+1 of 2 3/4) with a Knoxx industries pistol grip recoil reducing stock, heat shield on the barrel and top rail for optics. Looking for Glock 26 any year or series. Shotgun- $400, Knoxx Recoil stock- $130.00, top rail- $15.00, heat shield- $24.00. Looking to trade straight across. Only need 1 mag as I have a few kicking around.
