Can you fire a .40 S&W through a .45 ACP?

[Guest SkyDog]

This is what happens if you do.........(Glad it wasn't me!)

[eapking]

How's the patient doing?

[Guest TnDeerHunter]

ouch!!!!

[Guest TnDeerHunter]

How did the 45 stand up to the mistake?

[enfield]

I've done it -- I don't recommend it.

It's not too dramatic - the round goes 'pop' instead of 'bang', half an hour later the bullet reaches the target, you have to pound the brass out with a dowel.

Surprisingly, the cartridge came out the front of the gun and he finished emptying the mag before he realized what happened. Afterward he said it felt like a dud when it fired compared to the .45's.

Was that shot proceeded by the shooter yelling, "Hay ya'all! Watch this!!"

David has done it.

Surely you jest...hope no one got an eye put out!

You know what they say..."It's all fun and games...till someone gets an eye put out"!

Are you crazy? Are you crazy? Are you crazy?

More common is a 9mm running through a .40s&w

Looks exactly the same

41 mag though a 44 is pretty scary

same thing with a hot 44 through an old 45...which can be deadly

Hope he never has a squib.

When I was in the police academy there was an older guy in my class. The first day at the range he was shooting a .40 cal Sig and was having malfunctions.

No one could figure out why.

After about six hours the range officer noticed the pile of bulged casings around him and we all discovered he had been shooting 9mm through the .40 cal pistol all day.

Entertaining

I met a newbie at the range this week that had rented a 9mm and bought .40 ammo - he couldn't figure out why the cartridges wouldn't load from the magazine.. When I pointed out the problem, he said he thought they were interchangeable in some guns - thats why he wanted a S&W pistol.

Scary.

(He exchanged the ammo and did ok once that was straightened out..)

Didn't the range "associate" who I assume rented said gun and sold the ammo think this was strange to begin with?

[JPS]

Because of where it happened, I guessed that he either bought the ammo someplace else or from two different people. I'm confident they would have caught it if he had gotten them together.

Sometimes you will be ok sometimes it is disasterous..

A .308 fired in a .30-06 looks like a straight walled 45-70 with the -06 head basically the .308 ends where the '06s shoulder begins and the round will impact lower on the target the NRA did a whole article on this problem back in the 70's or '80s

38-55 is the same as a .375 Winchester DO NOT let that happen...the .375WIN will take the old .38-55 apart

.40S&W can be fired in a 10mm much like a .38/.357 situation but I prefer proper cal. ammo

I am thinking a .45GAP could go thru a .45ACP gun no problem either since most autos the extractor holds the case against the breech face..for those about to shout "they headspace on the case mouth" .. see the original posted pics above, the extractor made that possible not the case mouth..and the shorter cartridges mentioned have less or similar pressure.

Not something to be made a habit of.... I saw a shooter put a .38 Super magazine in his .45 (his excuse the guns looked the same) fired 1 round and stopped ... casing looked like pics at beginning of post..all was well and we all had a good laugh that day.
