Maybe the issue in the debate is defining what constitutes "SHTF".
I've been in war zones and for me, that is about as SHTF as it gets.
In those places, I was the security. I feared long guns far more than hand guns because they were used much more effectively against us.
I'm not saying that there weren't any, but I can't think of a single time I air lifted a wounded soldier or local national that was shot with a handgun.
1000's with rifles though....
Mall's in a SHTF scenario!? Not a chance. Street vendors at best. With a collapsed economy you're not going to have malls....
