Here is a video from a local news station in Toowomba, Australia. Due to the stringent gun control in Australia it took a bit of hoop jumping to get the go ahead to build an indoor range as part of a gun store. One of the major problems was to mitigate any chance of accident or suicide to shooters. According to the gun store owner, it seems you must be registered to handle firearms so this is one way of getting around that. If you look at the video, you can see that the handguns are tethered so that the muzzle stays down range. It is over reaching control but it is a system that is allowed in this Australian range.
