Hey! I picked up a nice stainless steel .45! It's in great shape, and will be going to the range tomorrow. I understand that this manufacturer went out of business a while ago (Arcadia Machine Tech.), but looking ahead, where can I possibly get parts for this gun? It is one of the smallest 45 auto's made (5 round) and operates only on double action, so the trigger is by design pretty heavy! I would like to replace the hammer spring eventually. Thanks!
