I have changed all 9/45 carry ammo to Federal HST. Used to use 9mm Barnes TAC 115gr now HST 147gr...45 Winchester Ranger T 230gr now 230gr HST. Felt like the overall ballistics of the HST bullets might be a little better. If I find I don't like the 147gr in my smaller 9's I will switch to HST 124gr. Hope this ends up being a wise switch.
