While I was nosing around a gun shop today I found one that is in VG shape. It has had a reblue job and someone added a modern front sight (Micro on the base) and an adjustable rear sight done ver proffesionally. Otherwise all the serial numbers match with the exception of the cylinder latch(37xx2) and the serial number is 37xx1. It has all the proper parts and markings which are readable. Inspectors mark of R.A.C. on the frame and cylinder and is marked "United States Property" and Colt D.A. 45 on the barrel. The bottom of the handgrip frame says "US Army Model 1909".According to the site I went to it was chambered for a 45 Colt cartridge which is the same as the .45 Colt (Long) except it had a wider rim to help with extaction. My question is Will .45 Colt (Long) work in it I am betting that this is what the previous owner shot.
