This answer is on point. Back in the 90’s while working for Brinks Armored, I had my door kicked in at about 4am in the morning. I jumped out of bed, grabbed my gun from under the bed, came up and racked a round while holding my gun on the door. I originally kept my eyes on the door through the hallway thinking they’d enter before I was ready with the gun, but they hesitated due to my dog barking and ran off when they heard me rack a round. In my mind I had decided to not bother looking for a weapon in the dark and shooting whoever entered, which was legal in California and most states. You’re just not that mentally sharp getting woke up early in the morning. Even God says you’re clear to kill someone entering your home at night, before guns even existed. And during the time of mine, a lot of home invasions involved armed men who would pistol whip and torture homeowners, especially targeting Asian immigrants that didn’t trust banks and had cash savings. So you have to assume you’re probably out numbered as well, so drop them as fast as possible.
