The Arsenal twin 1911 has two triggers. One trigger -> one bullet. I only see the one funky looking trigger on that thing.
Regardless of legality, it's still pretty useless.
Oh, I don't know. That's a pretty snotty little cartridge. I guess a lot of Deringers / derringers are sold in that caliber. Out of a
rifle, and just looking at energy (if that's all you look at) one of those rounds can approach .45 ACP foot pounds... let alone two of them simultaneously.
And the utility is in the eye of the purchaser.
But I think I'd rather be able to launch .22 Mag bullets successively.
And a dozen or more years ago I got severely "spoken to" for offering the idea that shot rounds would "stop" an attacker instantly, if properly placed and you didn't mind getting sued later by the now-blind attacker. I hesitate, even now, to point this out again.
