I run the HST 147 gr in my Glock 43 and M&P 9C and they are excellent. I've shot through an old pair of denim jeans with an old flannel shirt behind that and then a number of water filled milk jugs. From about 10 feet away the bullet made it to the 4th jug. Mushroom was perfect and weight retention was 100%. FYI the Speer Gold Dot 124 gr performed admirably also in these short barrel weapons.
