It's a Dan Wesson 15-2VH .357 mag pistol pack. It comes with a 2.5", 4", 6", and 8" barrels. I'm still trying to figure out what the wood thingie below the tool is. It's darker than the spare grip. It also has no flange, shelf, whatever you want to call it to catch on a screw head, so it does not go on the bottom of the spare grip.
