.45 Colt or .45 Long Colt what difference does it make anyhow? The term has become so generic it's a moot point.
Stuff like this happens.
The .22 Winchester Rimfire Magnum becomes the .22WRM becomes the .22Magnum becomes the .22Mag.
The .44 Smith and Wesson Special becomes the .44 S&W Special becomes the .44 Special.
The .44 Remington Magnum becomes the .44Rem. Mag becomes the .44 Magnum becomes the .44Mag beomes the Dirty Harry thingie
