I looked into the N8^2 version for a bit - they have a rubber coating that would/SHOULD prevent harming the firearm
I ended up not going with it, instead I went with a cheap nylon holster that I got at a gun show for a few bucks (one of the loops for the belt mount was coming off or something, I forget exactly, but it wasnt 'right' so I offered the guy a low amount and he bit).
I have it mounted below the steering column.
Out of my legs/knee's way when entering/exiting car, as well as driving. But still within arms reach.
Not seen from outside of the car, and where it is coupled with being a black holster and black gun, means it's sort of hidden away.
It works for me, I am satisfied.
