I agree. All the testing that has been done has been with 4" or longer barrels. All the street results come from police officers carrying full-sized duty weapons. But a lot of people, myself included, carry sub-compact or micro 9mm handguns for CCW. We've all heard over and over again which bullets work out of full-sized handguns. I'd like to know if those same bullets are recommended for for 3" barrels, or if the shorter barrel changes the game completely. Wanna kill these ads? We can help!
