Posts: 12 | The colt site is less than helpful. I sent them an email, but never got a reply. The 22/45 idea makes sense. See below: 4) Colt Service Model 'ACE' : Caliber .22 Long Rifle S/N SM 1 to SM 3,836 = Feb. 1936 to Jan. 1943 ( Between 1935 and Sept. 1945, 11,961 Colt Service Model 'ACE' pistols were made and their parts were fully interchangable with the .45 caliber M1911A1. 5) Colt Service Model 'ACE' : S/N SM 3846 to SM 13,803 = April 1945 to Sept. 1945 This information is from this site: http://www.sightm1911.com/1911Production.htm Also: S/N SM3725 to SM13803 Service Model 'ACE' .22 made, some gaps in numbering produced in 1945. Commercial production resumed in 1946. Note that the largest serial number shown is 13803. It also says that more were made, but there is no serial numbers listed. So, it looks like I have a frame , that was originally built as a .22, then was converted to .45 using a MK IV/Series 70 barrel, slide, & magazine. Does that sound right to you guys? Any idea when they stopped making the ACE .22s? The frame is in great shape and looks no older than the slide. The bluing matches perfectly. Is this a fun hobby, or what! Thanks for the feedback guys! |
