You’ve been here since 2004, you’re in Texas, and this is just now crossing your mind?

If this really is new to you, then take the recommendations of your real-world friends, not us. Why? They’ll be physically there to help you kit out, train along side you, coach and otherwise support you — all I can send are prayers and bits.
Nope, just now have the extra cash. I own a S&W Sigma .40 cal, a Ruger LCP, a Remington 870 I inherited from my dad (glad to see it’s recommended!), a Remington .22 bolt action single shot rifle (present for 13th birthday) and a ‘22 revolver, have the Air Force Small Arms Expert ribbon and the Navy Expert Rifleman medal (thanks to a reserve Master Chief who let me shoot the big gun - officers rarely got to do that when I was in). Didn’t know whether to buy an AR- type or another shotgun. I really appreciate all the recommendations.
