if it takes you 20 shots to neutralize a threat at point-blank, I don't think you should be allowed to own a gun

Fun thing in Australia, you don't need to be able to hit a target to get a gun licence. Licences tests are more focused on firearm safety.
- I mean, that's how it should be. Just like getting drivers license requires you to demonstrate you can drive safely, so should a firearms license.
- I'd say being able to hit an intended target and not just praying and spraying is part of firearm safety. Errant bullets can cause a lot of damage. It's been over a decade since I've owned a firearm but it wasn't for nothing that one of the four fundamental rules of firearm safety I was taught is "be sure of your target and what's behind it".

  Here you just buy the pistol, and a holster you like, and that's it.
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
- But 20? Like if you get shot once, hell, more than once, wouldn't you just more or less drop from the pain?
- I'm currently shooting myself periodically with 5.7 in order to boost my immunity to lethal rounds like 10mm.
- 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.
I think is just more of a fear response
Kind of like how people have a hard time taking off airplane seatbelts while panicking

Me, an old west cowboy exiting a salon: "Would be a shame if I had to draw this here hip-iron."

Varment Buscadero Up to No Good pointing his own pistol right at my chest: "Draw, you yellow-bellied sarsaparilla swillin' son of a gun. Imma gonna plug you good and proper, 'for ah take that there horse."

As the fastest gun in the west, I smoothly withdraw my six-shooter and plant all six rounds perfectly through his chest before he can even twitch his trigger finger.

"Gosh darnit. Them ammo rounds worth more than mah old sway-back, Trixie. Gonna have to visit the old general store and spend mah last plugged nickel, fore ah mosey on outta this here pig swallow."

"Exiting a salon"
You can skimp on ammo, but not on looks.
- I had just got my hair did and it bein' high noon and all figure I'd get me some ta eat.

20 rounds of 5.7x28 are like what, 10 to 30 bucks when bought in bulk? I don't know how that contrasts with carrying a $700 gun around.

Uh because the gun isn't consumable and the ammo is???
- Look at this guy, carrying around a used gun.
5.7 has gone down in price with more guns coming out it in. Buying 20 rounds of defensive ammo in 5.7 in 2019 would have easily been much more than $30. Still less than $700 but probably more than just handing over all your cash
- I want to say 5.7 went up 2019/2020 something crazy, there are old forum threads referencing pricing on Ammoseek from around that time, about $1.8 per round is the most expensive I could find.
  But yeah, I didn't even check the date on the original post.
- You get +AC from defensive rounds or something?
Just checked online: $0.40 to $1.50 per round. $8 to $30 for the 20 rounds.

This all could have been avoided with a Discworld-style Thieves Guild

Now go and pick them up like you did with nerf rounds as a kid

"They put $50,000 worth of bullets in his ass!"

Haha I love the idea of a PS90 ..it's fun when used safely at a range not as a cosplay element for the gravy seals. But the cost of the ammo has kept me from impulse buying one...I don't any any cool weapons currently but I also don't need them.

Because my trebuchet is full of threats.

This is the same reason I don't own a Five-seveN
Chiappa rhinos and 357 magnum aren't insanely expensive tho. It's tons of fun to shoot too
- What would you recommend for a personal weapon? Assuming the proper training happens too

It's not about the money

Yeah, it's logistically much easier to buy more ammo than to have to replace IDs, credit cards, family photos, etc.
- Y'all carry wallets still? 2 or 3 cards should be enough, that shit fits in your phone case.

Your money or your life!

Life please. Make sure and line it up properly though, I don't want to end up a vegetable.

I'd have to guess it'd cost like $40 to do that. Yeah.

Save the brass! Time to take up reloading in case you get mugged a lot.

You have to take in account though everyone you saved from being mugged

Yes but this round is meant for targets with body armor, and will kill people behind unarmored soft targets
- If there are any which it sounds like there weren't

While I don't condone deadly force a mugger asking for your wallet first is probably not going to stop there and so it may be better not to cooperate at all. Magdumping seems a little harsh though.

a mugger asking for your wallet first is probably not going to stop there
Source? That seems extremely counterintuitive
- Common sense. Someone who threatens you and tries to mug you probably isn't keen on not breaking the law. People who are not keen on not breaking the law might just be liars. I'm not saying all muggers will cut your throat after taking your wallet, phone and jewlery, but a good amount of them might just.
Really? I don't live in a country with guns. If I did, I would expect to get shot at if I attempted robbery. How could you possibly be surprised if you got shot?
- Much like this person being shot.

Dumping a mag on a criminal alright. Reloading and dumping another one might be a little too much.
Mugger still deserved it.

Just shoot them in their knee, murder isn't always justified plus you use only one bullet.
