I'm looking to buy one of these or something similar. Seen an older one today for 1200. It was at a local shop. The guy didn't know how old it was. Looked somewhat older normal scratches and all. Any recommendations on a brand, durability, and price range. Is colt the way to go? What could I look for to tell if this gun is gonna hold up, or will it need work. Just looking for tips or suggestions to consider when buying this type of used gun. Thanks!
