I actually heard a fantastic reason for carrying a second piece by none other than James Yeager. He said the best reason to is to be able to arm another person like a family member incase something really bad does happen. Never thought of it that way and it does make a bit of good sense. If you had to go and leave your wife, mother, father etc stationary during an episode, it'd give me a tremendous amount of peace of mind to know that they were armed. There are a lot of 'what it's' involved with that but it is food for thought, nonetheless.
I carry my pistol and a good assisted open knife
Reasons to carry more than one handgun on person
2 is one, 1 is none.
What if you need a throw down. (Purple)
You have 2 hands why not 2 guns.
That's what the guy training me says. But what's with the colors? I see people write green or purple after something they write. What's that all about if you don't mind a newb asking?
