They say it will arrive late this year.
Not sure how the short-stroke gas piston would work with a much smaller cartridge.
A pistol caliber carbine will be blowback operated. No need or benefit to the added expense and weight of gas operation.
Actually, a gas operated action would be lighter: a blowback operated 9mm requires a heavy bolt and strong springs.
Probably too stout for blowback. Unless it was a fancy HK style Roller Delayed blowback.Ok. Why not make one in 10mm?
