Assuming you paid a fair price for it when you bought it, used - and it's still in nice shape, you should be able to get what you paid for it. Typically guns will depreciate some, for the first five to ten years, then they will hold their value. More desirable ones will start to appreciate. Generally speaking, when you buy used, and if you "buy well" and the piece is in very good condition and you keep it that way - you won't loose money.
