A ring gun, a crucifix gun(!), a watch gun and others...

A sample image, a .38 caliber padlock...

Some of those are pretty cool. I can see them getting turned around though, and whoever uses it blasting themselves.

I like the sleeve pistol, but always wanted one like James West's that slid out from the cuff.
