I worked in a large gun shop back in the early 70's. We sold a lot of pistols and no one expected to need a "break-in" period before a gun functioned properly. Then came the Colt Series 70 .45 Auto. Customers complained about poor accuracy and guns not cycling properly from the get go. Colt's answer was that the Series 70 needed a "200 round break-in" for the new bushing to seat properly. I have never heard of any other gun that the manufacturer said a break-in period was required for proper function.
