10mm out of a .45acp?

[vpalace]

Can a 10mm round be safely fired out of a .45acp? I overheard a conversation but left before I heard the end of it. just curious.

They are entirely different cartridges - NO NO NO
.45 is a 11.5 mm

[JoeWilliams]

No. Not only not safe, not possible. The chambers are different diminsions, and the 10mm would not chamber in a .45.

That said, there are (or at least were) 10mms chambered in 1911s. Don't know if any still are. My experience with a S&W 1076 soured me not only on the gun itself, but the cartridge. I thought full power rounds were more than I could competently handle in a defensive scenario, and carrying the reduced power rounds didn't make any sense to me, too big a cartridge for the power.

Speaking of the 1076, has there ever been a bigger POS of a gun ever made? I don't think I ever got through a full mag without a malfunction. What possessed the FBI to adopt that thing, I wonder.

NO - The cases are different. Extractors etc. and so on.

You can shoot a 10mm/.40 cal. version of a 1911 and you can also convert a .45 frame to shoot 10mm/.40 if you swap the top-end (slide/barrel, etc.).

[pagunparts]

I too was disappointed by the S & W 1076.

I shoot an EAA Witness, a Glock 20, a Colt Delta Elite, and I even have a Contender barrel chambered in 10mm.

Thanks for the reponses everyone. So how about a .40s&w?

NO!

The only ammunition you should fire from a gun is ammunition that the gun is chambered for.

Can you? Sometimes, but not safely, nor should you.


With exception to AR style rifles shooting .223 Rem. out of a 5.56 chamber, likewise, shooting .308 Win from a gun chambered in 7.62x51


Edited to add: You can ACCIDENTALLY fire .40 from a .45, you can not chamber a 10mm in a .40, the 10mm case is longer.

I think that the confusion somes from the fact that a .40 S&W and 10MM bullet are the same, much in the same way that a .357 Magnum and .38 Special bullet are the same.

You can swap out barrels and springs easily to shoot .40 or 10MM from the same gun, but you can not switch between the calibers without changing hardware.

You can if you have a S&W 610 revolver.

You are correct. I should have clarified in an autoloader.

Do people still shoot revolvers?
