A 12 gauge Shotgun should suffice, but I do not recommend them if you have children in the house. My nightstand firearm is my Sig Pro 2022 .40 with Siglite night sights, Crimsontrace Lasergrip and XTI Procyon Tactical Illuminator. I don't believe all of that is needed, but the night sights are a must.
