Probably none of the above. Lots of cool factor, not enough practicality IMO.
Would rather have a shorter AR, possibly in .300, definitely a different sight, like an Aimpoint. I'd skip the UZI altogether. Benelli M2 shorty over the 870. Take your pick of handguns over the beretta, glock or 1911 for me. Something unsuppressed so you would point faster.
I chose the pistol. Easier to retain while checking the doors,windows and family members in the house. I wouldn't go outside. Might let the dog out though......
My initial thought was the Uzi because it's just so sweet and anything worth shooting at at 3 A.M., is worth waking up the entire neighborhood with a 30+ round burst. But after reading you have a golf course behind you, I'd go with the AR-15. The shotgun is cute, but not enough ammo for me to be confortable going outside with it. It's a bedroom or hallway gun to me. The pistol is a good choice, but if you have choices with more ammo, better caliber or both, go with them.
I think you just wanted to post pics of your bad a$$ weapons so we'd all be jealous ( well maybe not Dustin). Grab the one you are most comfortable with and is quickest to access.
I've never given much thought to a suppressor before reading this thread. In a home defense situation, a suppressor makes all kinds of sense: Quick thinking, not much time to don ear protection, kids in the house, etc.
