It's well known that anything above 50ft lbs is lethal so a 300ft lbs bullet is sufficient.  Why add weight and recoil trying to increase that.

It is? Show me some documentation please.

US Army used to consider 58 ft lbs the minimum to be lethal. That would make a .25 ACP a lethal round. I'm giving up. Whenever I challenge you you dodge, weave and don't provide decent reasoning. kthxbai.

Missing a folding shoulder stock.

Or a pistol brace, or whatever. I cannot realise any serious use of such ridiculously long "two-handed pistol" or "broadpistol"  or zweihander or whatever

the retro look is rather bizarre.

You know, calling that thing a montante is rather hilariously apt.

yup, montante were specifically used by bodyguards.
