I have a night side that has a second self on the side (toward me) and that is where I keep mine. It's "in sight" but out of sight at the same time to others.
I don't know where to get one in the stores, I found this at a garage sale and it looks like it was built especially for this purpose.
The trouble that I see with some of the ways that people place their weapons, even if it's in one of those "quick open" safes, is that you need to know your sleep patterns.
Me, when I first go to sleep I am a DEEP sleeper. It also takes me a few seconds to realize what is going on. That is for the first 4 to 5 hours. The next 2 to 4 hours I am in a very light sleep and will realize and react allot faster.
So the way that I set up is what I feel will work best for me.
