kfd82 thanks for the reply, I was thinking about mounting it under the seat also.
Theyd work great if you wanted to lock your gun in vehicle when you couldn't carry in some businesses. Just don't ever leave gun locked while driving around just in case you need to get to it real quick!
The main reason I am getting it is so I can safely leave my carry gun in the car while I work. Also when I go out with women I just meet I don't like to carry, I live in Massachusetts where most don't carry let alone own a gun so it's a good way to scare them off. I may just designate my SR9C as a car gun since I have no particular attachment to the gun and its not very expensive.
