Does anyone know anything about the effectiveness of the FN 5.7mm 31gr. round used in the P90? We are currently equipped with several P90s, and are supposed to be getting the 5.7mm pistol to replace our 40cals on tacops. I've seen what the round does on mild steel, but haven't seen ANYTHING regarding soft targets. I'm kinda leery of anything that small.....any help?
