Not sure if there is already a thread but what do you guys that carry the g42, what ammo do you carry. Right now I'm carrying Speer JHP

Totally nailed the intruder, but I almost blew her elbow off. Noob question - I am a new shooter/gun owner and I am using my gun for home/self defense. I have heard that I should practice my accuracy at 15-20 feet. Does anyone agree? Disagree? Thanks!
