>.30 SC actually has a reason to hang around as a niche cartridge
The market doesn't seem to think so, there are less .30 SC guns in consumer hands than there are .357 SIG guns.
>I've never even heard of .356 TSW
Well, .356 TSW is to 9mm what .30 SC is to .32 French Long. Grab a cartridge, make it way higher pressure, and now few guns can shoot it.

>30SC needs a stretched P32
That's never going to happen; the .30 SC people made the mistake of making it a 52k PSI cartridge, so the pressure is too intense for the pocket pistols made in 9mm, even more so for the pocket pistols made in weaker calibers. They should have just designed the cartridge around 38k-41k and had it compete against .380 ACP rather than 9mm.

>The problem there is the 1911 though, it just can't take a beating like a Glock or HK can.
All of those rounds meant to be better than .45 ACP can be chambered in any .45 ACP gun, convert your USP or Glock to it then. Oh wait, the cartridges still died and only handloaders care about them.

Ever since the 7.62x25mm destroyed a bunch of weak CZ-52s, there's been this myth that 7.62x25mm is some sort of super round. It's not; the guns chambered in it were just bad quality, and that's why they were breaking. It's an alright cartridge, but you can stop worshipping the 85-grain projectiles. 7.62 Tok PPU gets around 560-580 foot-pounds of energy, while .357 SIG Underwood gets about the same out of a much more efficient cartridge design.

>btw I'm a fan of the 30sc conceptually, IMO it needs a properly designed gun to rescue it from dying out. Not another re-chambered 9mm, nor something nobody will ever want to shoot.
It needs a Beretta 80x chambered in it.
