Since I have no kids. I use a nylon holster that is screwed to the headboard below the matress line by about 8 to 10" . I positioned it so it is in a perfect radius for grabbing when I am in my normal sleeping position. If someone was already in the room they would not even see that you were ready to draw on them. Too much time involved to open a drawer and unholster.
The one pictured has a velcro piece that you attach to the headboard. The holster is made of the other side of the velcro so you can position it at any angle. I experimented with it untill I found the prefered angle and then ran 2 screws thru the inside to secure it permatly. Then covered the screw heads with silicone as to not scratch my gun.
