Thanks for sharing all the others.
My Dad liberated this Colt when he retired from the USMC.
He'd had it since Korea (battle field acquisition), when he was a .30 machine gunner, later it went to Cuba (missile crisis) and Viet Nam.
I can't say for sure it saw action in either of the WWs, but it was in inventory for both.
It does have a pony on the left rear of the slide, and although it wears a 1911A1 grip safety, I have the shorter one as well, but with that one in place, it bites.
