Indeed, and the reason is simply because pistol calibers produce so much less.... Energy.
Exactly. But when you want and need stealth, the 5.56 does not cut it.
The 100 grain frangible work-around is just that. It still is half the power of a .45 standard ACP, if it is kept subsonic.
One of the really big problems with the 1st gen sub-guns is they are extremely heavy compared to locked-breach systems.
It should be possible to engineer a locked breach, integrally suppressed .45 or 9mm that weighs under 6 lbs, is compact, and is extremely controllable and accurate to 150 yards.
Why the big deal about sub-sonic? As if to say suppressors make anything go Pffft…
Having used several suppressed weapons for fun and games, both in pistol and rifle calibers up to 300WM, I see no real benefit as to “stealth”, once you go loud, everything stealthy is off. Further, the only real benefit of suppressed systems is for squad communications- and that is negated by other battlefield sounds, at least in my experience.
The slicky boys already have the tools they want in their toy boxes. Grunts needing stealthy sub guns? Along with M249s M16 family, M110s,M240s, M2010s and M2s? Hmm. Still not selling this former combat grunt/sapper.
Suppressed carbines and rifles and LMGs, I like. Subguns? For PSDs and Spec ops, okay, buy a few hundred, wait, we already have those....
Wasting dollars once again, like the many iterations of “tactical” camo uniforms.
Regarding heavy 22s, maybe if you run them as a pistol, but once you push them into moderate SS velocities from decent barrel lengths, they penetrate like crazy. I assume, assumed and will always assume any human target I am likely to engage, as a civilian or as a Solider, will always be armored. any other thought is dangerous.
