When the M1911A1 started coming into the inventory in the 1920s, did it eventually completely replace the M1911? If so, what was done with the M1911s?
Six of the seven changes made to create the -A1 were just a matter of swapping parts. All new -A1s were assigned SNs above 700,000, so an original M1911 would have an SN lower than 700,000. The one substantive frame change was milling out the frame on either side of the rear of the trigger guard to make access to the new shorter trigger easier, especially for people with smaller hands. Do any of you guys who regularly ran into the M1911s remember if the frames were modified?
