I'd love an I-frame in 30SC. Failing that, a J-frame in 30SC is a 20% increase in cylinder capacity, so for that niche application I think it's a good round. Similarly it might give you +1 or +2 in a tiny pocket auto, which would be interesting.
There has been a recent renewal of interest in 32 revolvers also, to get that extra capacity in a revolver and they're only gaining one round mostly. The 32 SC would seem to fit the same niche in a semi-auto that the 327 Federal Magnum fits in a small revolver. Sort of a 32 ACP magnum.
I have no idea if it's possible or not given the pressure the 30 SC operates at, but I wonder how it would have been received in a gun the size of a Bodyguard 2.0. Add a couple more rounds to the already impressive 10/12 round mags the BG-2 has and you're talking serious business then. The recoil might get your attention I admit. I'd say my 30 SC EZ kicks about like my 9mm version of the same gun. In a BG-2? Might be exciting.
My thoughts exactly on how the crowd/mob doesn't prefer something different other than the regular everyday standard. I love my 30 super carry and will be storing ammo when available at the right price. Shooting mine next to a clone G43x with a comp, I found the 30 super carry had less snap/recoil than the 9mm and had a good bit more than most .380's I have shot and owned. Final conclusion, to each their own.Whew. Tough crowd. I like mine - good shooter.
