Who doesn't like 'em? I'd love to have a functional one for my collection! I have a small collection of unusual concealable weapons (though none of those are firearms, unfortunately).
I've handled a Stinger; it's heavy, & well-made. I think the guy who had it still has it...maybe I'd better call him to arrange to shoot it! On the whole, it's better made & a better design than the .38 caliber pen-gun flare launchers I've seen (which could also fire a .38 Special cartridge, if you could tolerate the recoil).
