9mm vs .45 vs 40mm?

[JayFramer]

Friends, the net abounds with so many stopping power threads, which is better? 9mm, .45, or 40mm, for stopping an attacker with a single shot? Last night the news said a guy killed someone with a 40mm pistol, so there’s that. But doesn’t the army use the 9mm?? Please cast your vote!

9mm

.45

40mm

Recoil must be stout with a 40mm handgun, especially with +P's! Suppose it was carried IWB?

I was going to vote 40mm, but I think quick follow-up shots would be difficult, you know, in case the first shot didn't work.

A head hit with 9mm = head hit with 40mm.

Thanks for the thread! That made my day. At first glance I thought it was going to be the same old troll bait, and then..... Funny guy!

A head hit with 9mm = head hit with 40mm.

Except with the 40mm, there won't be much head, neck, or shoulders left intact.

Have to go with the 40mm although practice ammo is hard to come by.

I'm guessing the 40mm will exceed that 2200fps velocity that makes a rifle better than a handgun!

I just don't want to try to stuff that 40mm down my pants!
Not exactly what I'd call suitable for concealed carry!

I'm a Hellfire man myself.

9.1 lbs of HE at 1000 mph - the Hellfire wins!

Somebody needs to ask Kim JoGoon, he seems to prefer large calibers when executing officials, er, duty. Joe

Flip a coin. For me it’s more about the intangibles of the personal preferences regarding a specific gun/cartridge combination.
Personally I like .357 mag or 10mm, just because it’s what I like.

We've heard it all Bofors: The only thing that counts is shot placement. But that should be a piece of cake if you mount a MK 51 fire control system on your 40. It will be a lot heavier, and the gunsmithing charges for doing the mill work will be outrageous, but you won't miss.

Y'all act like 40MM is a big round

 

[pasound]

LoL I voted before I looked...

 

[gwpercle]

40mm or 40 S&W ...BIG difference .

The 40mm Bofors Anti-Aircraft Auto Cannon is just a bit more gun than the average person can pack concealed....they were hard to hide on a Navy ship.
If you do mean 40mm then yes it would be top gun in the stopping department . Knocking fighter planes out of the sky requires just a tad bit o stopping power.

9mm. That 40mm is just going to be too slow on the draw.

 

[Skeptic 9c]

There you go, quick and portable 40mm:

Who notes bigger is usually better.

Okay, ya got me. Read the poll, thought it was a typo, voted .45 (naturally), and then read Post #1. LOL!!!!!

Ya got me.

Most of y'all think artillery when y'all think 40mm; that's cute.

When I think of 40mm I am reminded how we gained fire superiority when fighting insurgent forces in the mountains. It wasnt with no artillery either, but with pure, unadulterated courage we carried the m320 (40mm grenade launcher) into combat with deadly effect.

I guarantee a body hit with one of these puppies is as good as a headshot with 9mm or .45acp.

Listen to me reminiscing. I'm starting to sound like my grandpa.
