UPDATED w/ Range Report. AMT Backup 45acp A friend of mine wants me to buy his AMT backup 45 acp with 1 mag. Neither he nor I have a clue to it's value. He is a good friend and I want to give him a fair price so we both feel like we came out on the right side of the deal. I have not seen the gun personally but I'd say it's probably like new knowing him. Anybody know the ballpark value? Thanks.
