Hitting the gym to become a swoletariat, looking to arm myself as well.
I've gone shooting before, and my Dad just bought a couple guns himself because of all the pogroms he's been seeing against Muslims in ingerland.
I'm based in the United States of Amerikkka, mods please let me know if this isn't allowed!
I personally can't shoot very well with Glocks, but otherwise agree with the other comments. Get a 9mm pistol, and an AR rifle in .556 or .223 Wylde. This is mainly about the ubiquity and relative cost of those ammo types, as well as the parts for the AR.
