Here is a manufacturer of some special holsters. They make two different models for your car, shown below:

The first one may be placed wherever you prefer on the car seat. It is held in place with a 4 inch square of velcro, which will adhere to any car seat material including cloth. The holster is adjustable up and down 5 inches and rides very snug against the seat. Color black.

The second one has a strap that runs around the car seat and a buckle fastens just behind the holster. It may be adjusted to ride under the seat and comes with a strap to secure the weapon when used in this fashion. Color black, the strap: color-grey, light brown, or black, depending on color of car seat.

They also have a bed-side holster which uses a 6 inch paddle (which is made of a stiff, non-slip material) to be placed between the mattress and box springs securely holding the holster and your weapon firm against the bed. Place it between the night stand, head board, or covers and if an intruder enters your bedroom, you have immediate availability of your weapon. Color black.

Neat ideas!
