All you need is your license and you have to wait for a certain amount of time:background check and yada yada...like almost a month I heard not sure. How bout a cattle prod instead of a stun gun. THose shits are tight. Or you go with mase. I got the illegal version though. The one that burns your eyeball out and litterally youll be blind for 2 days. I swear that shit burn even on your skin. Not fun but worth it so go check
