Stealth Swiftvault 2.0 is what has been near my bed for about a year. Well reviewed by the dudes who break into these type of things for fun.

Edit: easily fits a holstered fullsize with wml and an extra mag and flashlight. Dimensions are on the interwebs. Just a pocket holster with a thumb tab so I can eject the holster at will, but should accomodate an iwb even with a wedge etc.

I've also sandwiched a second gun on top with a second pocket holster for short term, not sure if that fits your needs.
