Stinger Pen Gun

RocketFoot @ PFOA has posted some great high-res photos of his Stinger pen gun chambered in .25 Auto.

(Click to enlarge)

.25 Auto is a very marginal cartridge. Winchester .25 Auto generates 66 ft lbs of muzzle energy. In contrast a .22 Long generates 67 ft lbs and a .22 Long Rifle generates 104 ft lbs!

    Does anyone know if it is legal to own without paperwork. I can buy a used one in Florida where I live. I have class 3 autos and a concealed weopons permit. Can I carry loaded in my pocket? Is it legal without paperwork? I have the maglite shotgun and it needed an AOW class 3 permit. Thanks for any help.
