This is similar to how I have mine. I have a Gould & Goodrich cheapo IWB holster with the belt clip. I put the gun in holster above the bed frame between the frame and the fabric on the bottom of the box spring. The clip just clips onto the metal angle iron frame. When you look under the bed you can't see the gun because it's tucked under so well.
