Can someone explain to me how you price a used gun because apparently I am out of the loop. I can buy a new gen 3 old stock glock at a local dealer for 491, a new gen 4 for 525, a new m&p full size for 560, and a shield for less than 450. When I go to sell a used gun, whether it's been shot or not once it leaves the lot it's used, does that mean that I automatically add $50 dollars to the used sale price? Thanks for clearing this up guys I am Just confused about seeing used guns for sale at above retail price.
