If it penetrates body armor, it won't be available to the public.

It's already available to the public.

Is the 'penetrating' round s certain type like the green-tip M855 5.56?

THE biggest drawback to 5.7 is the cartridge coating necessary for proper function. It has been mentioned above, but not emphasised enough IDT.

I wasn't even aware of that issue until I'd read about it somewhere else, before. It makes reloading a real challenge as you mentioned.

It’s been mentioned this is a great round for a sub gun. I personally don’t believe subguns have a place in weaponry except for perhaps a very small subsection. Moder SBR’s would serve the same purpose, with longer range capability to boot.

That's a solid point. There's a reason sub guns aren't really in broad use by military and police organizations like they used to be.

IIRC the SS109 has a steel core - meant to penetrate Soviet (Russian) body armor. It's why so many ranges ban its use.
