I bought a Rock Island 1911 and asked the gunsmith to replace the recoil spring to one a little heavier. He did but when I picked up the gun, and asked for the replaced spring, he said that he had tossed it, "I just didn't think about keeping it" he said. He said he would order one for me, it would take 2 weeks to get it. How likely is it in your view that an experienced gunsmith would "forget" and toss out a factory new recoil spring? I feel like he kept it and/or sold it and did not want to say. Am I too suspicious?
