Right now on Ghost Hunters (SciFi channel), they are in Astor Mansion, and one of the members is wearing a shoulder holster for something. I can't tell if it's a sidearm because the camera guys are doing a really good job of keeping it hidden (you can see the straps, but the holster itself is under his left arm). Anyone see this, and could maybe identify the rig? I can't say for certain it's a gun, but I can't think of anything else you'd wear in a shoulder holster.
