killing people wearing body armour within 100M from concealable or small weapons with high capacity magazines.

High capacity low recoil centerfire

You get 9mm performance in a gun that has less recoil and can also shoot a cf 22lr equivalent. Projectiles are pretty much all superior as well but the downside is the floor cost is higher than 9.It's a great woods gun. I hunt with mine and have supers to handle hogs.

There isn't. It and HK 4.6×30 were each designed specifically for a 1990 NATO requirement for a military weapon that was never mass-adopted. Each of the developers of those weapons and cartridges have tried to save face / sunk cost for four decades since then with various sales efforts, in the case of FN and their 5.7 with various handguns chambered in that round. Neither round would even exist on planet Earth if it weren't for the 1990 NATO mil requirement that never fully panned out (and was only ever adopted by a select few specOps and LE agencies)

Originally developed for compact, high-capacity weapons that could also defeat body armor. It succeeded, but then it got overblown and overmarketed because Fabrique Nationale wants money.

It was an attempt to SMG's issued to backliners who don't need a real rifle, 5.7mm is not supposed to compete with 5.56mm but 9mm which it outranges and out penetrates. It mostly failed because modern rifles are not as cumbersome as bolt action and battle rifles so you can issue someone a short barreled rifle with a folding stock and a few light weight mags of 5.56mm and call it a day without having to introduce a new pattern of weapon or new cartridge. So the current actual use case is convincing regular people to buy it because militaries won't.

Exposing 9mm metafag hypocrisy. Thier argument is always >projectile size doesn't matter >capacity is the only thing that matters Then you post a cartridge that by that logic should be superior to 9mm, and you get >no STOPPAN POWAH >no one needs more than 15-17 rounds and the real reason >waaah it's too expensive I wouldn't even care if you didn't want to pay a premium for diminishing returns from a performance standpoint or something, or you didn't like the handful of guns available in 5.7, but using those first two arguments in favor of 9mm vs any cartridge larger than it, and then disregarding them when talking about a cartridge that fits those criteria better just makes one's argument seem disingenuous.

5.7 40gr fmj is the ultimate self defense round for america because you can penetrate the fat armor of obese criminals where 9mm falls short. people always think about soft armor not being common but it's actually the most common armor in the form of obesity.

>Having to post it next to lol9mm to make it seem less pathetic by comparison Every time I shoot .45, 10mm, or .357 and go back to 9mm it feels like a fucking popgun. No wonder the average police shooting involves double digit round counts. I can't even imagine deciding to downgrade even further to a spicy .22.

It outperforms 9mm in a lot of ways but ideally it fits into a sub platform. PCC backpack guns have been getting shilled pretty hard lately and that seems like it’s best use case. The only real downsides are in a pistol platform small hands struggle with the ergonomics and in a PCC you can often get 5.56 rifles in similar size. Honestly I think Springfield is fucking up bigly by not offering the Kuna in 5.7 but what else is new.

I'd say give P90s with AP ammo to pilots who are flying in areas where body armor is present. Outside of unicorn logistics cases a carbine version of your country's service rifle is simply better for POGs

You can pack more into a mag and they're more effective against kevlar-only vests.

min maxed SMG round that also kind of fills a niche as a light rifle round like .22 hornet or a plinker on steroids

Anon03/11/26, 22:16No.64958892

Carrying twice as much ammo for the same weight. That's the only thing remotely interesting about the cartridge. 9mm can already defeat 3A armor with certain bullets and is otherwise superior in every conceivable way.

5.7 is a failed experiment. In real world use it was less lethal even when the shot count was over 4 times that of all other handgun calibers. The 22lr is demonstrably more lethal in use to humans than the 5.7.

Only complaint I have about my FN five seven is that you can't fire without a mag inserted so dry firing is annoying. might buy snap caps

The facts hurt some feelings >Basically every relevant country in NATO, except Germany, said the bog standard load was superior to 9mm FACT >It has less recoil than 9mm FACT >The trajectory is superior FACT >It's as quiet as a 22lr when using subsonic rounds yet has the performance benefit of a jacketed spritzer round that's center-fire FACT >It's legal to use on game in areas where other center-fire calibers above 22 are prohibited FACT >It makes people mad FACT >The loaded pistol is lighter than an unloaded Glock FACTBasically it's better in every way which is why people seethe.

every argument for 9mm vs .45ACP can also be made for 5.7 vs 9mm

Anon03/13/26, 07:15No.64964569

The actual use case it was designed for was to give rear-eschelon troops armed with pistols and SMGs a chance at defeating the Russian 6B2 vest issued in 1981, which consisted of a grid of 1.5mm titanium plates backed by Aramid.The problem is that two years later, the Russians started to replace the 6B2 with the 6B3 vest, which quadrupled the thickness of the titanium plates so that it could stop most ball rifle rounds, immediately rendering the whole project pointless.

I have a very odd and potentially stupid question. But would it be worth the money and time to reload for 5.7? If so then the initial sunk cost would likely pay for itself if you were vigilant about it. The lubricant seems like the biggest hurdle from what I read.

Something I've been eyeing 5.7 for is as a hd gun for my wife. Low recoil, ballistically effective, lightweight, easily suppressible, high capacity all seem to make for a perfect woman's hd gun. Thinking of getting the M&P one.

Anon03/15/26, 07:13No.64971902

Having lots of ammo in a mag, penetrating armor and leaving the tiniest hole on what's behind it.Pretty much with 9mm that achieves higher than 2,000fps, 5.7 is obsolete. I wouldn't field it, too expensive for low performance and low versatility.
