That's the reason there is a Ruger SR9c with a 17 round clip filled with Hornady Critical Defense ammo on the night stand next to my side of the bed. I know that at the range in this situation, I could have taken both their heads off without blinking an eye and I wouldn't have hesitated.
About 2 AM on January 2, a car alarm went off outside my room at a motel. I looked out between the curtains and could see nothing. I opened the door leaving the safety lock on. I could see toward the direction of the alarm and see no one. I stepped outside carefully looking both ways. As Humberto experienced, my level of heightened awareness was amazing and I felt no panic - full control of the situation. See next post.
