Went to a huge gun show and ran into these guys "Fast Holsters" the way it can mount in the car, home or office. My wife and I have it mounted to each side of the bed frame! Just grab and go. She even mounted one at her reception desk, yea she is a bad ass and don't back talk her or else, no robbing her ( her boss rocks) ! It cost about $20 and it can me mounted in in so many ways, my G19 Gen 4 I can mount it side ways or mount it handle down and the mount on top of the rail. Here is a link in case you all wanna Check it out!
Good luck and Godspeed to you all!
