I think more thought needs to be put into a lot of folks HD weapon of choice. a 1911 loaded with 230 grain? Damn, that is a lot of HD, plus you need to worry about where the bullet goes once you pull that trigger. Don't get me wrong, if you are good and assuming you have had some experience with the drastic increase in heart rate, breathing, etc., etc., you should be good to go. Personally, my HD weapon of choice is two actually. First is a nice Shotgun (assuming it has been converted into a HD weapon). You certainly don't want to have to move tactically with a big ass shotgun. But if you rack it and the bad guy doesn't leave immediately, then chances are he/she/they are armed and intend to do bodily harm to you and yours. Which brings me to my second (and favorite) HD weapon..Bond Arms Snake Slayer IV! It comes in either .45/.410 or .38 Spec./.357 Mag. Great for concealed carry also...total length is only about 5" or so...
Again, I am not trying to be a dick...just my two cents!
