Never-Empty Double Gun (NEDG) Carbine Stock For Two Pistols

A company called Florida Discount Guns Inc. have developed a concept pistol carbine conversion stock kit which would accommodates two separate pistols at the same time. The idea is that if one pistol jams or the magazine runs empty, there is a backup.

The kit is just a concept at this point. They are trying to fund the development of the project by taking pre-orders from military or law enforcement agencies.
