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.
