Why? What purpose does it serve to type an inaccurate label? Would you type "9MM long luger" because someone made a 9MM Kurz?
Save yourself some typing and help the newbies from making a mistake.
I use .45 Long Colt because that is the traditional name for it. Although SAAMI says it is just .45 Colt. Most people know exactly what I mean when I say .45 LC, but may not know that .45 Colt means the revolver cartridge while .45ACP, oops, make that .45 Auto is for automatics.
Yes, I know there have been quite a few revolvers chambered for the .45ACP cartridge.
Now the reason I don’t say 9mm Luger long is because that is a made up name.
