A few nights ago, my door blew in violently at about 3 AM. As a student, I live in a small studio and the foot of my bed is only 20 feet from my door. I had forgotten to throw the lock and the latch is unreliable. I was truly ashamed of how slowly I reacted, I just sat there like a lump for a few.
I was pretty happy that when I did grab the Beretta and swept my porch with my TLR-1, I realized I had automatically swept off the safety without thinking. Training!
