That really looks like a lot of fun! Maybe if I was actually capable of hitting anything with a handgun (or if I owned a revolver(s) instead of a semi-auto compact) I'd give it a try.
Do you allow spectators, and in particular one who's a semi-professional photographer?
We allow spectators. Cameras are welcome. If your interested, at any monthly club match there will be plenty of guys who will be willing to lend you guns and gear so you could try it.
