I've seen this video in the past but thought I'd post it for those who may not have seen it.
It came to some very interesting conclusions,some I already knew,and some I wasn't aware of.
I have seen this data before, but it is good to be reminded.
I think the biggest takeaway from this is to go with the handgun you know and are good with, as long as it is not a "mouse cartridge" type.
I do disagree with the idea that a handgun is the best weapon for a bugout. A weapon is not just for defensive use, but also for obtaining food. And the sight of someone carrying a rifle would be a considerable deterrent to someone who is unarmed. The best defensive situation is one in which they bad guys decide you are more trouble than you are worth.
Interesting conclusions and I do not disagree with all of them. However, as a primary bugout weapon, a handgun can be a very risky choice. Even an enemy armed with a carbine or shotgun/slug combination would be able to stand you off from out of pistol range, if all you've got is a handgun, unless you are capable of making two hundred yard shots with it. For bugging out a safer bet is an AR-Pistol or even better, paying for the tax stamp to build a short barreled AR rifle. With a 7.5" or shorter barreled AR, one can easily conceal it in a backpack, broken down, and still reach out and touch trouble makers at 300 yards and better. As for caliber to go with in such a weapon? Right now the .300 AAC (Blackout) is, in my opinion, the only way to go. With that caliber one can hunt medium game and defend oneself quite effectively. A final benefit of the SBR platform is interchangeability of upper receivers in many calibers with one lower receiver, on the fly.
