>>2097 Bear is a man now! We'll celebrate this once you've fired your gun and survived.
Don't forget about a decent hearing protection and glasses unless you're wearing glasses anyway. Stuff ricochets back, we've had lead shrapnels hit us from 25m. Doesn't hurt but you don't want this stuff in your eye.
Obviously you save the expensive hollow tip for the bad guys and shoot with the cheapest ammo you get. Ammo brand absolutely doesn't matter until you git really gud.
First thing you should do now before you hit the range is practice muzzle discipline at home. This starts with opening the case your Glock is in. I assume you got the nifty black Glock case with your gun. Memorize to which side the muzzle is pointing if you open the case. Whenever you open the case, the muzzle must point to a safe direction. Not your stomach, not at other people, not out of some window where kids are playing outside. You open your case at the range with the muzzle not pointing downrange at the bullet catch and you've already screwed up. The muzzle must ALWAYS point at a safe direction.
NEVER assume if a firearm is unloaded it is therefore 'safe' to do with it as you please. Do not threat an unloaded gun differently than a loaded one even if you know it’s unloaded. That’s a matter of habit and prevents unsafe behavior. Keep your finger off the trigger. It has no business there while you handle your gun. Only once you’ve taken aim at your target and made the decision to fire, your finger may touch the trigger. You've seen the shit Alec Baldwin did. This must never happen. A gun is always to be treated like a potentially deadly tool. Host's instructor always said guns were made for a single purpose - to kill people efficiently. And they're damn good at this.
