It's literally worn as a ring, like knuckle dusters. The bullets are only like 5mm, but you could replace them with pure dust pellets. I did it for No Returns, which is a knuckle duster-ring. Four of those in a row, upscale a bit to be a touch bigger. Full things on my weapon page if you want to read it.
