Why does everyone say ".45 ACP"?

I ask for .45 acp as the old timers want to give you .45LC as they cant help it i guess.

Next time at WalMart id like to ask for this ammo
"John Moses Browning's Greatest Achievement, The Forty-Five Automatic Slash Autoloading Cartridge Slash Colt Pistol Caliber Slash Pistol Format."
And then have them ask me if its for a "pistol or rifle?" and reply "slingshot".
 
Sounds cleaner and more streamlined.

Since I am not charged by the word saying "forty five Ayy Cee Pea" costs me no more then saying "forty five auto;" there is nothing about me that is 'streamlined' so I feel no need for an aerodynamic vocabulary; sometimes it it more important to be clear then it is to sound cleaner.

Of course I will call it a "45 auto" as often as I call it anything else...
 
Why does everyone say ".45 ACP"?

Well, as has been mentioned, it delineates whether the speaker is talking about the Automatic Colt Pistol cartridge, the .45 Colt (sometimes called "Long Colt"), the .45 Auto Rim ... or now the .45GAP.

Who calls the .44 Magnum the .44 Remington Magnum, though? ;)

Or the .38 Spl the .38 S&W Special?

If one manufacturer wants to call the .45 ACP a .45 Auto (and at least couple do), who really cares, as long as the owner/user really knows which is the proper ammunition to load and use? I mean, really?

People can sometimes get too wrapped up around the axle when it comes to using proper cartridge names.

I must admit, however, that one day I felt a momentary wave of dismay when a young cop came to the range and was telling some of his peers that he had come by to qualify with his "gat". :rolleyes:

Words mean things ... and effective communication does require a consensus when it comes to definitions ... but sometimes folks get a little persnickety about things.
 
45 ACP or 45LC,45 Auto Rim, 45/70, 45 Super or 45GAP

If I was to order 1-4K rounds of 45, I'd better be clear what type for 45 cal. I actually need with so many available or you're gonna pay to ship 3 times... You can't shoot the LC, Super, Gap or Auto Rim out of your 1911 ACP so being specific is critical.
 
Parabellum is comprised of two Latin words:
"para" meaning "for", and
"bellum", meaning "war"
Not to be a bad guy, but the two Latin words in that phrase mean "prepare for war."

Para comes from paro, parare, paravi, paratum, (prepare), and it is used in the imperative in that form. The designation "parabellum" came from the Latin adage "Si vis pacem, para bellum" (the sig of more than one person on THR), which is translated as "if you want peace, prepare (for) war." The "for" comes from the accusative ending on bellum, not para.

P.S. Sorry for the threadjack.
 
Look at the markings on the barrel that are visible through the ejection port. Here's my Browning High Power, made in Belgium in 1951 by FN Herstal.

I looked at the different brands of .45 Auto/ACP ammo I have. Federal, WWB, and Blazer all have ".45 Auto" on the box. The Sellier & Bellot has both ".45 Auto" and ".45 ACP" on the box.
 
When I saw that, I didn't think much of it except as a typo. But it also shows up when he refers to the 7.65 m/m. (m/m=1):)
 
I just call it Colt 45. Works every time...
That's too vague and could be construed as a .45ACP or a .45Colt and is exactly why some folks feel the need to use the incorrect .45 "Long" Colt.
 
I actually pronounce ACP phonetically, really confuses people over 40 and one guy asked why I was trying to speak Klingon.

People call it that because they do, same reason people say soda, soda pop, pop, or as the illiterate Texans say, Coke :D

As for people getting confused about about the differences in 45's, doesn't happen often. If you walk into a store and ask for a box of 45's, 99% of gun stores will hand you a box of 45 auto, the other 1% is screwing with you.

If you ask a guy what engine he has in his car and he says, 350, no need to elaborate as everyone knows it is a Chebby engine, no one is going to think it is the Chrysler 350, big block made in the late 50's early 60's that later became the 383 for those of you who are going to argue that it is a stupid analogy because Mopar didn't have a 350.
 
because that is the name of the cartridge... adding the ACP is not a matter of preference, NOT adding the ACP is a matter of preference. It is like saying Jon rather than Jonathan... 45 ACP is the name of the cartridge with ACP standing for Automatic Colt Pistol.... 45 is its nickname...
 
Because my Thompson, and my AR45, and all but one of my 1911s, are all chambered in .45 ACP... The one 1911 I have that isnt chambered in .45 ACP once was.

With the popularity of internet acronyms, its actually easier to type .45 ACP than .45 auto, because for a lot of us, the acronyms are second nature.

why do people call a standard transmission a manual transmission, or worse a stick shift?
Why do people insist on calling manual transmissions "standards," when automatics have been standard equipment, for just about everything, for years?
 
You got to be kidding. I read this whole thing. Some got it and a lot didn't. It's called "PROPER NOMENCLATURE". Calling,writing or saying it by it's proper nomenclature insures that no mistakes are made. Considering the amount of various .45 cartridge types and styles out there, that would be enough reason to use the proper term for a particular caliber.
 
Why 45 ACP...

out of reverence for the folks who gave us such a fine legacy of course...

But then again, by that standard, we might call it 45 JMB....

Yet the Colonel was the man with the money (and the factory)...

Should we venerate the artist or the patron of the arts?

I love to wax philosophic, though it seldom gets me anywhere.

Isn't the trusty old .30-30 likewise a "de-name-branding" of the venerable .30 WCF (Winchester Center Fire), coined by the "me-too" manufacturers that saw the merits of the cartridge?

What something is called is most often a product of one thing.... MARKETING
 
I use "45 auto" (Phonetically) and "45 ACP" (Spelled letter-for-letter as an acronym)
