I'd like to know what home invasion threat can't be stopped with a hand gun. Grizzly bears? Ok, got me there.
I've never understood any civilian application of the idea "use my pistol to fight my way to my rifle." Who is in between my and my rifle? How did they find out where my rifle is? If I stop them with a hand gun, why do I need the rifle?
I thought the saying was just a cute way of saying your rifle is a more powerful fighting tool than your hand gun.
