Now it is time to impart some crucial information: NEVER use 147 grain ammo in a 9mm pistol! There was a stupid fad for 147 grain hollowpoints a few years ago, and many were suckered into buying these weak, worthless and malfunction-prone rounds. I don't care what you've heard: never use any 9mm hollowpoint heavier than 125 grains. 147 grain hollowpoints often jam in many popular 9mm guns like the Browning Hi-Power, SIG, Beretta 92, S&W and Glock. Ignore the gun magazine hype and stick to what works. If you want to gamble, go to Reno. Don't gamble with your life. 147 grain ammo sucks.
