Follow-up shots are very different. It takes a substantial amount of practice to pull off multiple .357MAG shots in rapid succession. They must be fun to shoot recreationally, or for hunting but I couldn't imagine using them for SD... especially indoors with no hearing protection. Although I can imagine you wouldn't need to actually HIT anyone with the first shot. Upon hearing this thing he'd jump out of the window, 5th floor or not. Even a 9mm is jarring, a .45ACP is nearly intolerable without plugs... I can imagine this would make your eardrums bleed. That being said, it would be a great gun to carry into the deep woods if you can't take a rifle. I doubt he bought it to carry around. It's not that kind of gun.
