My primary reason is that I hunt with a handgun
I like to hunt squirrels and deer with a handgun
I watched to many western movies and found out that when you run out of bullets you can throw your sidearm at what ever you can't hit with the bullets..It's like 2 weapons in one....
If you you run out of bullets you can use it like a hammer
And beat the snot out of what you were shooting at
