Flashlight or Shot Gun?

"Gits Nasty? Git down to business," beams the SHOT Show booth boy after showing off the FMG-9, a concept weapon that can switch from a simple flashlight to a Glock-style submachine gun in one easy flick of the wrist. Designed by Magpul, the FMG-9 is currently in prototype phase, and there's no guarantee whether it will be released or not, but I guess it's one for the personal protection peeps. And nervous dog-walkers.
