In the mid-1980's the U.S. military adopted the Beretta 92FS to become its standard issue sidearm. They immediately called it the M9. Dozens of manufacturers produce a Model 1911. It's also known as the 1911/A1. It mainly is known to come in .45 ACP but also comes in almost any number of other calibers. A Model 70 Winchester rifle can come in almost any caliber from .22 to .458. The military's rifle is the popular M-16. It's also known as the M-16A1, M-16A2, M4, AR-15 and it shoots the .223 round which is also known as the 5.56 mm.
Still with me? Good grief, I don't even know what I'm talking about! All I know is that guns should have names, not numbers. Not names like SIG Sauer (why is the sig in all caps but not the sauer?) or Garand or Walther. I don't think these people know how to spell. I think guns need more nicknames so I know which one people are talking about. I like "Ma Deuce" or "Burp Gun" or "Grease Gun". Even "Tommy Gun". I know what that looks like. It even has more nicknames: "Trench Broom", "Chicago Piano" or "Chopper". Any of them are better than "Thompson submachine gun".
I know of at least one "Poodle-Shooter" and a few called "Ol' Faithful" or "Tiny" or "Big Boy". I'll just call my pistol "Bill". It's short, plain, and nothing fancy. It fits. I don't have a name for my shotgun but maybe "Mudfence" because nothing can be pretty with that name. So, what do you have? "Padre" or "Buzzsaw" or "Cereal Killer"? Maybe a "Screamin' Meemie" or a "Bugle"? Just don't tell me you have an AR-10A4 SPR or I'll get ol "Loudmouth" after ya!
