5.7 is known to be pretty terrible for its "stopping power" for lack of a better term. Its a handgun round design to penetrate body armor. In doing so it had to make sacrifices in bullet dimensions and weight. It performs similarly to a .22 magnum round which is a frankly wimpy cartridge meant for small game like rabbits.

So 20 rounds to stop a human isn't stretching the truth too much.

Sounds like the wrong gun to carry for personal defense

[–] JackbyDev@programming.dev 12 points 1 year ago (2 children)

But 20? Like if you get shot once, hell, more than once, wouldn't you just more or less drop from the pain?

In high stress situations people frequently don't even realize they got shot until after the adrenaline wears off. In my EMR course they trained us that we need to physically check for bullet wounds ourselves if a shooting was suspected because you can't rely on the victim knowing that they've been shot.

That's why mag dumping is more or less standard practice in survival situations. Sure, 1 bullet may kill the person, but it probably won't do so for several minutes and until then you've only pissed them off. So you shoot and keep shooting until they actually drop. Which, when you're talking about a particularly wimpy round like the one above, can take far more bullets that most people expect.

Kind of like how I unload an entire can of bug spray at the wasp that came into my house.
As a European this is my only frame of reference.

This is one of the most American comments I've ever read.

Sounds fair, makes sense. I'll keep this in mind in the (hopefully unlikely) scenario where I need to defend myself with a firearm.

Where one would actually need to use the gun, perhaps adrenaline would come into play?

I'm currently shooting myself periodically with 5.7 in order to boost my immunity to lethal rounds like 10mm.

[–] Shard@lemmy.world 2 points 1 year ago

Make sure you switch to hollow points occasionally. It helps with the lead immunity as well.

I did not know that (I probably should have figured it out though based on the physics and the tiny little bullet) when I professed my love for the PS90...I just thought it was fun at a range... And now I learned I might as well been shooting a money gun.

5.7 is certainly a fun one to shoot and it feels great.

But once you try knocking down steel targets with a 5.7 and you start to realize its limitations
