The 147 grain bullet in the 9mm Luger cartridge was, and still is, a bad idea.
It was originally developed as a subsonic loading for use with suppressors, often suppressed submachine guns.
It is a terrible performer in a pistol when used as a self-defense load.
While the 147 grain bullets can be very accurate, it's terminal performance is poor.
Not long after the 9mm craze hit American Law Enforcement, the "heavier must be better" bad idea fairy appeared. After some spectacular failures with the 147 grain slugs, most agencies realized the 115-125 grain weight range is where the 9mm projectiles need to be.
