    Further deliberation. . .

    Maybe if they were pitching this thing as a .380 replacement - a .32 Super, if you will.

    The question then becomes:  How are the chassis of the various little locked-breech pocket rockets like the Ruger LCP, Glock 42, Smith Bodyguard .380, Sig P238, Kel Tech, etc... going to handle the zip of this round?  It's potentially the .40 S&W wear and tear all over again.

    If they could make it work in the dinky-dinkies, maybe they've got something.  Plugging in the same 1.5 pound gun I used in post #22 for sake of consistency, a .380 is generating about 2.5 foot-pounds of recoil, maybe a tad less, vs. a bit under 4 for the .30SC and roughly 5 for a 9mm.  Some engineering required, but probably not moon-rocket level stuff.

    My guess is that this would present the same problem they had a hundred years ago when they put the .380 into blowback guns engineered around .32ACP - - shootable, but with the potential for unpleasant snappiness.

    I'm TRYIN' to find a point to this thing. . .

    There are simply not enough differences in this cartridge from others that are available.  It does not appear to do anything well enough better than 9mm or .380 to make it worthwhile.  At least not for me, but admittedly, I value practicality over novelty.

    Nope. 

    You say that now but wait till they come out with a derringer barrel for it. 🤣

    I could see a “braced pistol” PDW style gun with 40+rounds in a magazine smaller than an STANAG 30 rounder. Ultra lightweight, low recoil, and a whole lotta bullets. 

    That would be cool. Kinda a modernized CZ Skorpion.

    I found this interesting.
    The chambering generates nearly 50,000 psi of pressure and, with modern design, offers performance not possible just a few years ago. The 100-grain Federal load will provide 347 ft-pounds of muzzle energy; Remington’s 100-grainer offers 336. Meanwhile, the Speer 115-grainer generates 338 ft-pounds. Those numbers compare well to the 381 and 313 ft.-pounds produced by Federal’s 124-grain and 147-grain 9 mm loads, respectively.

    Taking the energy equation and solving for the velocity we see that the 115 grain Speer GD load trucks around the neighborhood at about 1150 fps (PF ~ 132). That's not bad, I just hope the guns don't fall apart early from those high pressures.
