Why not just go to a 10mm a whole new caliber and its distribution would be tough right now

 

when standard 9mm will blow your lung out of your body, who needs 9mm Magnum?

 

To blow both lungs out of the body........

 

There is already the .357 Sig?

 

that would make one heck of a PDW round

 

Mauser did the select-fire, detachable magazine Schnellfeuer Broomhandle variant in the 1930's, also compatible with the hot 9mm Mauser Export round.

 

CorBon has the 9mm 115 gr +P+. Closely approximates .357 mag ballistics @ 1350 fps.

 

Yeah, agree. Heck, my SD 9mm is 124 grn JHP @ 1250.

 

Never heard of the 9x21? Or the 38 Super?

https://en.wikipedia.org/wiki/9%C3%9721mm

https://en.wikipedia.org/wiki/.38_Super

 

Or 9x23 (the newer 9x23 Winchester, not the Largo stuff) or 9x25 or 356TSW.

There was actually a 9mm Winchester Magnum (9x29) made back in the '70s.

 

some low weight 357 sig rounds are race cars.. 80gr at 1750fps

 

There already is. 9mm +P+ - Check the Federal HST rounds. It's about as hot as you are going to get without going to a .40.

 

I have a couple cases of the Federal LEO 115gr +p+ if I could find someone local to trade with id do it. Otherwise maybe I need a scorpion evo pistol..

 

Ive had some Spanish 9mm SMG ammo in the past that would probably fit that bill. Less than 2000 rounds of it trashed the upper on my SWD M11/9mm. The gun also ran noticeably faster/harder than any of the other 9mm I shot through it. Ive shot a bunch of different makes of surplus 9mm that was supposed to be SMG only ammo, and that stuff was the hottest of the lot.

As was mentioned, 9mm +P+ has been around all along and the mid-weight stuff is basically equivalent to 357SIG in its standard loading with the same weight bullet.

After fooling around with a lot of this kind of stuff for quite a while now, Ive come to the conclusion that its not worth the extra money and wear and tear on the guns to try and soup up something that's not really going to be much different souped up. And nothing in 99.5% of the pistol calibers, +P+ or magnum, etc, is going to pierce a soft vest. If you want more power, there are better things available in a similar sized package.

 

.38 Super? It will send a 124 gr pill at up to 1,500 fps. Nearly identical bullet. I'd call that a 9MM magnum.

 

9mm magnum would not fit reg 9mm, but reg 9mm would run in PDW.

Would not work like rimmed catridges. 9mm Cartridges are head spaced on the case mouth.

 

Not completely true, the extractor holds on to the case.
Shoot plenty of .40 in 10mm barrel. Zero issues. Not just me either.
Now, i would not depend on a setup like that for my life, but fine for a little range plinking.

 

If I remember my ancient history
The 9mm Mauser export round was 9x25
Since the round was developed in the early
1900s to push a 127 grain bullet at 1300 fps
I’m guessing there would be room to hot rod
it a bit

unfortunately it would need to be a magazine
In front of the trigger guard like the c96 mauser

also there already is a 9mm magnum
It is 9x29

 

2 words.... The Judge

 

fun gun for sure but not a PDW

 

9mm magnum would not fit reg 9mm, but reg 9mm would run in PDW.

38 Super Ballistics Chart | Ballistics 101

almost what you want

 

Take the 500 S&W cartridge. Make it rimless. Neck it down to 9mm. Load it at hot as possible. Design a pistol that can handle it. Hold on firmly, but not too tight. Ignore that song saying to hold on loosely, but definitely don't let go.

Call the round the 9mm Joepocalypse Bidenator Ultra-MAGAnum, and call the pistol the De-Lung-Alizer 2024.

 

Done, 9x25 Dillon in a Bren 10.

 

9mm magnum would not fit reg 9mm, but reg 9mm would run in PDW.

They do, sort of, it's called .357 Mag (9.07mm)

 

Exactly...

 

I just read this entire thread. So which round is better?

 

They did....the 9x21 and the 9mm Largo if your hung up on .355 diameter. They were even available for the 1911 for a while, dont know if they still are.

 

I had one of those back in the day, didn't take me long to figure out ammo was hard to come by, and I got rid of it

 

If you want “moar” than 9mm offers in your PDW…there are already 15-20 options. No need to limit yourself to 9mm diameter.

Personally, I’d kind of like to go 7.62 Tokarev, but the .357 Sig is a nice modern alternative.

And with the modern guns, you may as well just step up to 7.62x39 or 5.56.

But, on the other hand…...45 ACP makes suppression a viable and effective option.

 

I wish someone would offer something new domestically in 7.62 Tokarev so more shops would carry it. It is a pretty hot little round, but isn't as easy to locate as I'd like. I have a few things chambered in it and don't shoot them often because it is harder to find and flings the brass who knows where so its hard to recover it to reload. The only issue that I'd have with it for personal defense is the penetration. As in, it may overpenetrate.
In my opinion 9mm is a pretty good overall round just as it is. Anything 9mm cartridge other than the 9x19 has the same issues as 7.62 Tok when it comes to availability from what I've seen on the shelf.
Personally if I feel like I need a bit more thump, I'd go 45 ACP also. Its got enough mass and slow enough speed to pretty much deliver all the energy into the target and I see it stocked often.

I know someone with an AR pistol in 5.56 and one in 7.62x39. They tell me the 7.62x39 one is actually a lot more pleasant to shoot than the 5.56. For just shooting at the range that's great. For defensive, I'd think I would sacrifice my comfort as the shooter for it to be even more uncomfortable for my target. But I'm not sure between 5.56 and 7.62x39 which would have the advantage for defense.
The good thing about the pistol rounds though is the weapon size doesn't have to be as physically large.

I don't know that "...the 7.62x39 one is actually a lot more pleasant to shoot than the 5.56.", they're both loud as hell out of short barrels and throw large fireballs, but the 7.62 doesn't have as bad of a "crack" (for lack of a better term) or concuss the same as the 5.56. I can (but don't) shoot an AK pistol with just muffs, but I want plugs and muffs with short ARs, especially indoors or even covered ranges; I tend to wear plugs and muffs a lot more these days now that I'm getting older and maybe/hopefully a touch smarter. The 5.56 doesn't lose as much velocity from short barrels as some like to claim but the bullet itself is more dependent on velocity than the 7.62x39 which retains more energy by virtue of a heavier round (K.E. = ½ mv 2); you have a much better selection of bullets for 5.56 though and it's easier to tailor your load for the gun. They're both fun to shoot though. 😁

 

They need to start making LESS new fandangled calibers , that's what they need to be doing.

 

When I was messing with the 9x25 Dillon I was getting close to 2K with 115gr pills out of a 6" barrel and they would about vaporize a racoon - now THAT'S 9mm Magnum...

 

The vaporization of vermin is always a goal that needs fulfilling.

 

don’t need a mag when you hit where you aim. practice.

 

Well sure. 9mm has dropped grizz and moose, and I don't consider myself unarmed with one.

But sometimes a little more HP is nice. Reassuring. A lot more is better; but a moderate amount more is better than nothing.
