5.7 x 28 Glock

Because the last and only pistol designed by glock was the 17.

Kel-tec makes a handgun in .22 magnum, completely different cartridge.

I am a weak little bitch. I will buy anything Glock tells me to.
Seriously.

Hate to be the bearer of bad news there champ.

No they didn't; if you're thinking of the PMR/CMR, they shoot .22WMR, a rimfire with just less than half the pressure.

That said, it's not all that much pressure by rifle standards; less than 5.56, and only 25% more than hot pistol cartridges like .357sig.
And it's a really skinny cartridge, which means that the bolt thrust is actually a little less than 9mm. (And that a given size barrel has more wall thickness to deal with the pressure.)

The only real issue is that it's long as fuck, so they won't fit in any existing Glock frame. They'd have to make an extra-long action longer than the 10mm/.45 guns, and nobody wants to hear all the handlet whining that would result.

What we know for certain about the potential future Glock chambered in 5.7x28 is that it won't be named the Glock 57.

5.7x27 GAP

COUGH G46 COUGH

Oh, spare us.
As stated, the 5.7x28 runs at double the pressure of .22WMR, and it has way more powder space. So it curbstomps .22WMR, how could it not?

Yes, the ballistics on your box of .22WMR (referring to a 24" SAAMI-standard test barrel) look suspiciously similar to what 5.7x28 delivers out of a pistol.
But if you compare 5.7x28 out of a rifle-length barrel, to .22WMR out of a rifle-length barrel, 5.7x28 does way better.
And if you compare 5.7x28 out of a pistol-length barrel, to .22WMR out of a pistol-length barrel, 5.7x28 does way better.
Even if you compare 5.7x28 out of an intermediate barrel (say 10", like the P90), to .22WMR out of a similar-length barrel, 5.7x28 still does way better.
And none of this is the least bit surprising to anyone with a functioning brain.

If you want another cartridge that performs similarly to 5.7x28 in a similar-length barrel, your only options are HK's 4.6x30, and .22 TCM. (And .22 Hornet, .218 Bee, etc., I suppose.)

Damn, if only 5.7 owners could take a joke like they do criticism. Oh, wait.

Yeah bud, God forbid anyone have a remotely serious discussion on Jow Forums. Great joke though.

*golf clap*

>Would you buy one?
In a heartbeat.

Almost definitely, hopefully it would revive the dying yet useful cartridge.

To take a joke seriously:
.45 GAP "worked" because .45 ACP is a rather low-pressure cartridge, only 21ksi, while normal pistol cartridges run around 35ksi. So by boosting the pressure to .45+P levels (24ksi), Glock was able to retain essentially the same performance while removing some powder space.

To fit 5.7x28 into a 10mm/.40 action, you need to shorten it about 1/4", and boosting pressure enough to compensate would jack it the already-high pressure to standard rifle-cartridge levels (55-65ksi); then you end up with too much force for your standard locking action, and you're redesigning the whole gun anyway.

I'm afraid the only practical option is to do what .22 TCM did, and make the case fatter to compensate for the short length -- thus forfeiting 5.7x28's capacity advantage.

They should still modify the cartridge. Keep pressures around 35k but increase the case diameter to about .390 and bullet diameter to about .355, shorten the case slightly to, oh I don't know, maybe 19mm, boom fixed.

no man it's all about those .30 caliber bullets

i want a .50AE glocknade. who would be brave/crazy enough to shoot one?

you mean a little 3D printed plastic piece of shit like the FN 5.7?

heh

nice buzzwords granpa

i welcome new guns chambered in 5.7. ive said it before but i thin the round would really flourish with more "investment" by other gun companies. yes i know 5.7 has a specific purpose and ammo available to civilians is pretty much neutered but still, its a fun little round

>i want a .50AE glocknade

lol thats badass as fuck. never seen that round for sale anywhere though, probably would be reload only

yeah okay I forgot about 50 GI

5.7 pistol is the best pistol ever made and 5.7 is the best caliber ever made, glock will never make anything to that degree of quality.

And it STILL gets its ass kicked by overpressure .38 Special. Fuck man, if AP were legal that'd be a different story, but 5.7 is the "why bother" of the modern cartridge world.

AP ammo is one benefit (although it actually does just fine in readily-available solid copper loadings, youtube.com/watch?v=xbMlxdp1cSw ), but the other benefits are low recoil and high capacity -- great for a full-auto P90, not so great for the rest of us.

It's a great round for what it's designed for, but it's mostly "why bother" for normal handguns. Even if you expect to be facing armored opponents for some reason, lightweight solid-copper bullets in more-or-less normal calibers (9mm+P or .357 SIG) also defeat IIIA.

At that point, why not make a revamped 7.62 Tok? Not that I'm opposed to that.

Fugg yes

You know how proofing barrels works right? Nothing special needed for 5.7x28. The bullets don't weigh shit

All they would need to do is down load the cartridge. It doesn't need that much pressure out of a pistol because it's wasted powder

Effort and cost. Honestly if LEO won't buy it they don't really give a shit.

The 5.7 slide is aluminum covered in polymer user

Besides the retarded case taper and the fact that it's not really good at anything?

high pressure is very important in pistols because you don't have much distance to accelerate the projectile

Terrible self defense round. Might as well carry a .22 magnum. Worthless.
