Ok guys, I'm new to all this hangun stuff after years of hunting with rifles and shotguns I actually got an corporate/ executive protection job and have since been issued a Glock 19/9mm. I'm planning on buying me one of these for my home as well. I love this gun. My question is, I am looking to carry a second gun on one of my ankles. I'd like it to be small yet still have takedown power. What would you guys recomend? Which Glock?
