Hello All, Just wondering what forge markings I should look for on a carry handle to know it is a Colt and it is not another brand or a knock off Chinese one. I know there are a bunch of markings out there, just didn't know if there was a complete list I can reference to. I have seen some for sale at gun shows with an A-# or AB marking with claims that they are off of Colts. Just wanted some sort of conformation. As always, your help is greatly appreciated!
