Awww, cute. And deadly.

2" long working revolver.

Yeah, even though it's theoretically lethal, on its own it's a novelty. The part that's potentially scary is the existence of 3mm ammo. You could build a sports watch that held two or three of these bullets and used electric "firing pins" to get a wrist-mounted weapon that might well get through security (you take off the "watch" and stick it in the security tray, then get it back after you're wanded through). Press and hold one of the buttons for 10 seconds to fire all the bullets at point blank range. Just make sure your hand is in the right position so you don't shoot yourself. ;)

Ilike it! It could work, looks like my sister's sort of thing, but at only 513 feet per second, and such minuscule bullet mass, a BB gun has a greater chance of killing someone.

If you want scary, slightly bigger, but a lot more useful, there's these:

http://pengun.com/ which DO work and look like a pen, or even better:
http://www.naaminis.com/ which makes a tiny .22 revolver that uses normal factory ammo. I've used a .22 successfully on everything up to a rabid Doberman with good effect so long as the head was hit properly.

I still wouldn't use either of these things for 10 meter match, obviously...

I wonder if the super-tiny comes with adjustable sights?

I knew a WWII Black Ops vet who told me he had used something very similar to take out select targets in the aftermath of the war.

Scary and effective stuff.

Dunno about effective, but keep in mind that that's pretty much all a pen gun is good for. One careful shot at extremely close range. No sights to speak of, after all. It's obviously not much of a defense weapon. Too slow. The setup time makes it only useful if you already know you're about to use it. Particularly the models legally sold as handguns due to the folding. So you can either deal with clandestine assassination or hurt yourself badly through a shot to your own leg (happened more then once).

The old OSS (pre-CIA) was infamous for such contraptions. I think the pinnacle was 'Aunt Jemina', edible yet exploding pancake flour. Never took off, obviously.
