9 mm Fun Gun
At this year's Shootists Holiday one of my fellow shootists showed up with a 9mm Gatling gun that he'd picked up and loaded a bunch of ammo for. It runs off Glock magazines and dumps the empties right into a bucket for easy reloading. He put together quite the outfit with special built wooden crates for everything, including "1250 Rounds 9mm Gatling" stenciled ammo crates. Here's yours truly giving it a run at the 40 meter chickens.
