Besides my main gun safe for shotguns, AR's, and various handguns, I keep a GunVault safe by the bed. Like you, I have a tottler running around.
I personally like the GunVault. It has a 4 finger combination to open, and is spring loaded to open. I've had it almost 2 years, and love it. You can hardmount it to a wall or bedframe, or just have it sit by the bedside.
I had a sensor malfunction one night on my alarm system, and the alarm activated. From a dead sleep I was able to access my gun within a second or two.
There relatively inexpensive.
