"I realize that common usage serves the purpose of communication just fine...."

No, it does not. Words have specific meanings that can be critically important concerning safety issues.

"To say “.45 ACP” has absolutely no possibility of being misconstrued and is in fact still used quite widely."

To believe that the .45 ACP, 45 Auto, .45 Auto+P and Cartridge Ball, Caliber .45, M1911 are the same cartridge because their dimensions happen to be similar is an irresponsible misconstruement of a high order. Each has a different maximum pressure specification. Three of those cartridges were/are pressure tested with entirely different units and techniques whose units are not interchangeable.

You seem to be advocating a violation of the first rule of firearm safety. Every carton of ammunition manufactured by a SAAMI member incorporates some form of the warning, "Use this ammunition ONLY in firearms marked and chambered for use of this cartridge."

Read the headstamp, stupid! If your firearm is marked "45 ACP" then that is the ammo you should use. As an aside, virtually none of the gunwriters or gun nuts in general seem to be aware that the U.S. military has NEVER chambered ANY of their firearms for either the 45 ACP or 45 Auto. Not the 1911 series pistols, not the 1917 Revolvers, not the Thompson SMG's, not the Reising SMG, not the Liberator Pistol and not the M3 (Grease Gun) SMG's. ".... I don't feel any need to nitpick others...."

I corrected my kids inappropriate grammar even though I full well understood what they were trying to communicate. It is a responsibility of the educated to help raise the levels of others, especially when safety issues are involved. So yes, I will point your irresponsible misinformation posted on this forum.

"Only someone chock full of themselves would insult another person's intelligence"

I didn't insult your intelligence, of which I have little input to base an opinion. I did point out your lack of knowledge about the subject of which you wrote, because of the safety issues involved.

"You might know more about firearms than I do..." Yes

"....you are incredibly unpleasant to talk to...." Only because you came to a factual discussion unarmed

Warning: Do not shoot 45 Auto factory ammunition in the following firearms:

Taurus PT1911

Kahr P45

FNP45T

EAA Witness 45

Check those headstamps, stupid!

I believe the proper response your nonsense was already posted.

Note that manufactures list ACP, ACP +P, etc.,yet that same ammo is listed as .45 Auto elsewhere.

Read the headstamp, stupid! If your firearm is marked "45 ACP" then that is the ammo you should use.

Indeed, so why would a loud mouth, know it all, tell me otherwise when I referred to .45 ACP? A little bit of knowledge and arrogant people do not mix well.

"....you are incredibly unpleasant to talk to...." Only because you came to a factual discussion unarmed

As visually demonstrated for you several times now, and oddly admitted by yourself. You are wrong in stating that .45 ACP is wrong to use. All that you've actually added is that there is more than one .45 designation. Thanks for stating the obvious Sherlock. And I'm pretty certain that the reason you are so unpleasant concerning this, is because you are generally unpleasant. Get a grip.

No one was having a technical discussion,but sense you started one and are wrong, note that .45 ACP and .45 Auto are used interchangeably and both have a max pressure of 21,000 psi. No one anywhere has ever damaged a firearm by shooting .45 Auto in a gun marked .45 ACP, or vic versa.

Why don't you go haunt some trapdoor shooters and blow a gasket telling them not to fire modern .45-70, or cruise Gunbroker and remind everyone that the 7.62 CETME chambered Mausers shouldn't be fired with .308. I'm certain you would still be annoying, but you might at least serve a purpose.

Perhaps it would help you to answer this question.

If “.45 ACP” is a non-existant, obsolete cartridge/term, why are so many firearm/ammunition manufactures listing and marking their firearms for it and further stating that the .45 ACP and .45 Auto are the same cartridge?

a. They are stupid and can’t read headstamps

b. They are pushing a dangerous product

c. They didn’t realize that SAAMI officially designated the cartridge .45 Auto back in the 1920s

d. They undersand that .45 ACP is common usage and identical in application to .45 Auto, and further understand that “ACP” is what most people prefer.

What about M2 Ball versus .30-06? How can I be firing both in my Garands? Let’s not even think about shooting .38 SPL in a .357 right, what would the headstamp police say?

Since you were also incensed at the thought of using a “foreign” term for an American product. It might interest you to know that the A-51/P-51 had the American name “Apache” before the British came along and named it “Mustang”, after which the name took and even the older A-51s and P-51As were called “Mustang”. There is also the curious issue of whether the A-10 is a Thunderbolt II or a Warthog.

Now its clear that if you are correct, then the entire firearms/ammunition industry is incorrect and millions are in great peril. You could continue to point out how wrong I am, but wouldn’t your time be better spent going after the manufacturers? They probably have know idea how smart you are, but I’m sure they will change everything once they hear from you.
