It's a .45 U.S. Army Model of 1917, commonly known as an M1917, made in 1918. A correct original one should have the text U.S. ARMY MODEL 1917 oriented vertically on the butt and the text UNITED STATES PROPERTY underneath the barrel flat. All M1917s originally had 6-1/2" barrels.I have a S & W .45 ACP w/ "S & W D. A. 45" stamped on the right side of the barrel...
It is nickel plated.
Checkered wood grips.
SN#634XX
1960/61. Is it stamped 28 or 28-1? I ask because -1's are rare and 1960/61 is the time frame for them.since this thread keeps on going can I ask about my model 28 serial number S213528
