I have a S&W .45ACP which was a basic 1917 model, though this one is one of the 1937/38 guns made under Brazillian contract & bearing their crest on one side, S&W logo on the other. It is a fun gun to shoot. I have full moon, half moon & 1/3 moon clips for it. Also the S&W can be fired without clips, but empties then require punching out unless they fall. Most Colt's had the cylinders bored straight through so do require the clips for firing as well as extraction.
