As one who has several 9mm handguns, I have pretty well settled on the heavy 147 gr Jacketed hollow points for all of them. Have tried the 115 gr, the 124 grain, and everything from the old Browning HP, down to the little Kel Tec PF9, the heavier weight bullet just performs better, at least at reasonable defence distances.
If I was concerned about 50 and greater yard targets, I might think different, but at the 10 to 25 foot defence distance, they have great penetration, plus open up well. Recoil i snot brutal, even in the less than one pound semi auto, and a real fluffy kittens cat in the Ruger Blackhawk .357 / 9 mm version, so up until the next "new wonder bullet" comes along, I'm satisfied with my choice.
