70-year-old solution:
Snap-on gunstock for a .45
We already have the cartridge they need-the 45 auto. All we need is a modern carbine to fire it.
Memory tells me a German (Austrian? Swiss?) arms mfg. introduced something that would fill the bill a few years ago. Caliber was under .22 with a muzzle velocity up in G-d’s country. The needle like slugs would easily penetrate body armor. The whole thing was only slightly larger than a normal pistol and had a (I think) shoulder stock. I haven’t time for the research just now, does anyone else have a better memory than I do?
It’s the FN FiveSeven
One word:
Bullpup
Bill
Thank you Single Stack. Does anyone know any reason that the FN FiveSeven wouldn’t do what the Army needs it to do? Duh. It’s on the shelf. I finally took a look, they’ve got some nice bull pup designs for the cartridge too.
Ah! That’s got to be it! We haven’t spent enough money on studies and development yet!
Why not a kel-tec Sub-2k style weapon in 223?
The KT folds at the breech into a package ~16x~3x~6 and fits in a standard briefcase with no problem (don’t ask ow I know...)
Deploys in under a second if mag is in and bolt is locked to rear - click/slap/rock&roll.
Further, the Sub-2000 comes in 9mm or .40 and interchanges mags with a number of pistols, so it would be easy to make a bunch that took the Beretta mags if that’s what they wanted…
