shafter, I'm not so much worried about this guy..
as I am the 6'5" 275lb punk who counted on a football scholarship as his ride in life, and didn't get it, now on the street, meth/coked up, taking out his frustrations on the world as he sees fit.
While drugs sometimes make an attacker less aware of their injury and thus able to continue an attack physical size does not. Someone who is 240 lbs and shot is no better off than someone who is 150 lbs and is shot.
Do you have any proof that this is the case?
I don't know if it's from video games or movies but a lot of people have an unrealistic view of the effectiveness of certain rounds. Some people seem to hold the view that the .45 ACP will knock someone back several feet while a 9mm will bounce off them and they'll keep coming. Also regarding rifle calibers some people seem to believe that the .308 can cut someone in half in one shot while you'll have to fire a whole magazine into to someone with a .223 to even get their attention.
At the same time while rifles are more effective than handguns, shot placement is by far more important. Numerous people have survived rifle rounds because the rounds missed vital areas while numerous people have been killed by handgun rounds because they hit something vital.
While you should prepare for the worst not every criminal you may encounter is some unstoppable killing machine which can take round after round and keep going. Although I know it's happened before it's pretty rare for someone unarmed to keep coming out someone armed who's shooting at them and disarm and kill them. Most of the time when someone who a firearm is killed by someone unarmed it's because they were disarmed of the firearm before they were able to use it. I don't know where the idea comes from that some muscle bound PCP user is going to be charging at you and taking numerous rounds and not stopping. I've heard many more times of someone unarmed being shot and killed trying to disarm someone who already has a gun out and ready than I have about someone unarmed charging forward and disarming someone who is has their weapon out and ready. I think it's probably in the same category of people who believe that women shouldn't have guns because they'll just be disarmed by an attacker. Obviously this has no truth to it but people still believe it.
People can tell themselves a million times that they can be shot and keep going but when it comes down to it no one is really sure how they'll react. Before I deployed to Iraq I remember some of the biggest loudest guys would talk about how tough they were but when it came down to they were worse off than the people who were just modest and normal about it.
I think the idea that you need a high capacity pistol like the Springfield XDM (19+1) for self-defense or home defense is in large part influenced by movies, tv, and video games as well. People have been faring just fine with 5 shot revolvers. Yes it doesn't handle every situation but neither does a high capacity 9mm pistol. It'd be like saying everyone needs a pickup truck in case they need to carry a lot of things, at the same time you lose passenger space so everything is a trade off.
I prefer larger calibers like my name implies but I'm not going to write off say a .380 or .32 because some gun writer or tv show shows it as being weak and ineffectiveness. I'm going to do plenty of research on the subject first. The only reason I would be hesitant to get a gun in .32 is because there are now tons of pistols about the same size in .380 ACP. People nowadays are not any more resistant to bullets than they were 60 years ago. There's a report I read a while back about how the 5.56mm round used by the Army was actually less effective because a lot of our enemies were so thin. Instead of the bullet having enough time to yaw it would pass right through the target. If the target had been more muscle bound it would have been more effective.
