It’s basically a mp7, that they say will cost $1000 in 5.7X28mm.

I want one, do you?

No, if I have to handload AP rounds for a pistol so it can defeat armor, I want to handload sabot rounds for the 460 or 500 magnum, that way I can at least defeat body armor meant to stop intermediate rifle rounds.
Granted I have to get the sabot bullets manufactured by specifications and can't just buy it from a factory. However, I'm pretty sure there is no factory selling 5.7×28 steel core bullets for handloading, so I would have to get it personally manufactured anyways.

5.7×28 is bad for literally anything other than penetrating pistol grade body armor.

Also the reason why you can't buy AP ammunition, at least in the US, is that AP pistol ammunition is illegal to sell or transfer. You can however make it yourself, and AP pistol bullets are not illegal to sell or transfer.

If you get it chambered in pretty much any other pistol caliber, it might be worth getting. I haven't priced semi automatic sub machine guns, mostly because they don't interest me, so I'm not if it' a good deal.

Edit:
Fucks sake I missed a section of the law.
(17)(A) The term “ammunition” means ammunition or cartridge cases, primers, bullets, or propellent powder designed for use in any firearm.
means ammunition ((or))
TLDR, if you want to handload AP ammo without a license, you literally have to make the bullet yourself.
Although there may still be some room for legal cheesing.
(C) The term “armor piercing ammunition” does not include shotgun shot required by Federal or State environmental or game regulations for hunting purposes, a frangible projectile designed for target shooting,
(C)a frangible projectile designed for target shooting,

Thanks for the write up, didn’t know that stuff about the ap rounds legalities.

I work in an environment with lots of people and am worried about over penetration, any suggestions for a backpack gun?

Frangible ammunition in conjunction with wider calibers reduces the risk of over penetration.

Sort by actual diameter.

I've heard far too many horror stories of 9×19mm Parabellum failing to stop criminals. While it does have a decent caliber size of .355 inches, it has too little energy at an average of 500 ft⋅lbf. Granted it's very hard to stop someone when they're being fueled by adrenaline, and starting to go into shock.

A revolver chambered in 44 magnum can be excellent, the energy range is wide enough that you can buy ammunition that is of a low enough energy that it is comparable to 10mm auto, meaning overpenetration can be minimized.

10mm auto is another good choice, its caliber is .4 inches and has a smaller but still decent energy range.

A revolver in .41 Remington Magnum also exists and is a decent choice. It's in between 44 and 10mm.

If you're after a semi-automatic sub machine gun, which seems to be what you want, there are a few choices for 10mm.

Finally the Heckler & Koch MP5 chambered in 10mm. I was unable to find this for sale anywhere.

There's also an "Omega 10mm pistol" from Atlantic Firearms, however it looked questionable so I didn't bother linking it.

The Vector seems to be the cheapest choice, but always watch a few youtube videos, and read some online threads from owners to see if it's reliable.

Unfortunately, there aren't many options for large caliber, "intermediate like" energy pistol cartridges. 50AE also exists, but I'm pretty sure that will be too much for your purposes.

Edit: I swear I've had this conversation with someone before.
