I'm with Puma Guy. If I were going to go with something of a similar ilk I think it would be the Bond Arms Defender...though at 20 ounces net it isn't exactly credit-card size.puma guy wrote: Fri Feb 23, 2024 9:35 am A friend bought a Switch .22 mag repeater. He test fired it into the end of an oak log. It bounced off barely leaving a dent.
On the semi-auto side, there's also the tiny Seecamp LWS 32. A little over half the weight of the Defender derringer but in the slightly anemic .32 ACP. Still, though, in a package only 4.25" overall length and 3.25" tall you get a 6+1 capacity.
