ok so I have decided to carry federal hydra-shok ... for now we will see what happens once I get into testing them at the range. my question how important is the weight of the bullet. I will be using them a xd40 subcompact, and I am new to shooting handguns, been more involved with shotguns and rifles for hunting the rest of my life. Anyway I have been looking around and it seems that many LE and government organizations use this hydra-shok ammo. I am just uncertain how the weight of the bullet will affect the shot. figured what better place to come for advice. BTW these rounds would be used for home defense, as I do not really like the idea of carrying a 12gauge goose gun around a dark house if I think something maybe up ... seems like a little overkill. any advise welcome.
