What about ease or difficulty of rapidly firing multiple rounds?
Since many of these posts have focused on untrained (or undertrained) individuals, which type of firearm could such a person use best in an actual home defense situation--IF a malfunction did NOT occur? I am, for the sake of argument, going to eliminate malfunction as a point of concern and examine another potentially important issue. Remember that we are talking about an unskilled person shooting at an intruder, most likely in a darkened house. The intruder is believed to pose a life/bodily-harm threat; this threat must be eliminated. In such a mission, where failure may cost us our lives, who among us at THR would shoot one shot in the dark at a shadowy figure that we believe means to harms us or our families? Am I the only one who imagines my opening salvo consisting of a three shot burst? It's dark. I can't see if he's got a gun pointed at me. I'm not going to shoot once and wait to see what happens next. I'm not talking about shooting someone for trying to steal my TV. If I'm shooting someone, it's because I am convinced he's coming to get me or my loved ones. I'm gonna shoot him until he falls, and then probably shoot a couple more as guarantors.
Even for skilled persons--which, remember, we are not talking about--which is easier to bring back on target for an immediate follow-up shot, a 9mm auto or a .357 Magnum revolver? Which is easier to fire rapidly while remaining on target?
Before someone comes along and posts that one shot is all that is needed from a .357 Magnum, I will again recall our attention to the fact that the shooter in question is untrained (unprepared). Someone with little shooting experience will have serious doubts about being able to hit an inteded target, especially in a life threatening situation. Would such a person, totally lacking in confidence, really want to rely on a single shot (after which he/she would be deaf and blinded by muzzle flash)? Can someone lacking practice rapidly fire a .357 Magnum?
I fully appreciate all of the posts about jams and malfunctions. It has not been my intention to minimize that issue, but only to examine a different issue. Some failures are not the fault of the gun, but of the bullet (bad primers). Everyone who chooses to arm himself with a gun should become well-acquainted with the functioning of that gun. It would be tragic if someone armed with the means to protect himself died because he couldn't figure out what to do when his gun misfired. BTW, I have a Glock 17
