When I have to leave my pistol in the car I have a lockbox under the seat that is cabled to the body of the car.
Sure somebody with a bolt cutter can remove it, but I can live with that risk.
me too, am thinking of putting a bracket on my console by right knees that i can clip a Bladetech IWB holster to for my GLOCK 42. can lock it in lockbox and will have a 26 IWB with me on right hip. probably illegal in Denver where a carjacking is most likely.
