Are there any bays that allow movement while shooting or is it all under covered areas from a firing line? Are there rules against drawing or working from a holster?

I've been told there is a range just around the corner from them called "big salty" that does action shooting but I can't find any information on it.

They don't allow movement while shooting. This is more of a place for sighting in a new scope or teaching inexperienced shooter gun safety.

id just go to the desert for that

To my knowledge there are no areas that allow moving while shooting. If you find a place like that please let me know. And I don't think there are any rules about shooting from a holster as long as you're being safe. You sound like a fun guy to go shooting with. Quick draws and 3 gun practice by the sounds of it.
