I bought a couple vinyl coated bicycle hooks and mounted them right above the bedroom door. My 12 ga hangs right over the doorway on my way out of the bedroom. High enough that the grand kids can't get to it and handy as heck if I need it in a hurry. If someone didn't know it was there, it would rarely be noticed.
Amen...and ditto!
Glock on the night stand...Remington 870 Tactical mounted inside and above the door to my closet...3 steps away! (The Glock is in case I don't make it to the Remington...and becomes then it becomes the back-up for the wife!) Remington is loaded with #3 Shot...
