What Is the Best Handgun for Home Defense?
The best home defense handgun is a full-size or compact 9mm with a weapon-mounted light, night sights, and loaded with quality hollow point ammunition. Top choices are the Glock 17 or 19 with a Streamlight TLR-7A, Sig Sauer P320 with a TLR-1 HL, or Smith & Wesson M&P 2.0 full-size with a Surefire X300. A light is non-negotiable, you must identify your target before shooting.
What This Means for Your Setup
Home defense situations happen in low light, under extreme stress, and with family members potentially nearby. You need a handgun that is reliable, has sufficient capacity, allows rapid target identification with a weapon light, and fires ammunition that reduces over-penetration risk. Getting any of these wrong can have devastating consequences.

Why a handgun over a long gun for home defense:
- Maneuverable in hallways and doorways

Why some prefer a long gun (AR-15 or shotgun):
- Easier to shoot accurately under stress
- 5.56 fragments in walls and may over-penetrate less than 9mm (counterintuitive but tested)
- Higher capacity
- More terminal effectiveness

Build Impact
Set up your home defense handgun and leave it configured, do not constantly swap lights, sights, and ammunition. Mount the light, load the magazine with defensive hollow points, and place it in a quick-access safe near your bed. Practice accessing the safe and presenting the firearm in low light. Train with the weapon light on and off. Keep a handheld flashlight nearby as backup.
