Today BTAP and I were testing his two new pistols, and I offered to do a pain test. So I got proper eye and face protection and stood approximately 8-10m away from BTAP. First he used the Hi-Capa (with Excel .25s, all I had at the time, and Coleman's Propane), and it hurt like a bitch, although the effects weren't immediate. Then we tried the M190, from a bit furthur, and once hit, pain was fucking INSTANT. There was lots of shouting and swearing, and laughing from BTAP. The guns left two big red welts, even through a shirt.
Awesome pistols BTAP!
