Lock 'n Load With R. Lee Ermey

[Yournamehere]

The "Colt .38" wasn't a Colt New Service as there aren't any chambered for any .38 Caliber bullets. The only thing it could be is the Colt 1894 Army DA, or some revolver that no one has ever heard of.

Edit: It might not even be an 1894, I can't find an example with a 4 inch barrel. Of course the gun described and the gun used might not be the same thing, so the gun seen might have just been some random .38 Caliber Colt.
