Start with non-lethal options like lights, cameras, and reinforced doors. If you go for a gun, a PDW (like an AR pistol) is versatile. Avoid shotguns—they’re heavy, loud, and not as practical as people think. Training is key no matter what you choose.
I’d recommend a Glock 17 with a red dot. Simple, reliable, and easy for beginners to aim. Keep it loaded and ready.
Get a good alarm system with motion sensors and lights. A dog also helps as an early warning system. Firearms are your last line of defense—focus on keeping intruders out first.
