I carry a 9mm. Always have and always will. I use Federal HST’s 147gr and so does my wife. It does t matter what someone carries if they can’t hit the target they are shooting f at. Is 9mm the best? No. But I believe with the new ammo tech it is a fine round to use. Many people won’t use anything else. But I don’t have anything against other calibers either.
Federal HST is an excellent choice for any pistol caliber.
