Thank you every one for the quick responses. As messed up as it sounds, I am looking forward to more relaxed gun laws in Hawaii, relative to CA. 8+ month for CCW approval, handgun roster, and fixed mag ARs are brutal to deal with. My guess ammo cost will be pricey, any regulations against me bringing ammo into the state? Another enjoyable California law....
The actions bays at KHSC (public range on Oahu) does host USPSA/IPSC competitions. NO IDPA events. There are a few different USPSA/IPSC groups. It used to be that there was a competition every weekend, but after the shutdown, only a few groups have started back up.
If you are DoD (.mil or .civ), you can join Schofield Rod and Gun Club. They have rifle and pistol ranges, along with shotgun. I haven't gone in years, but another opportunity.
Are the action bays the "cowboy" shooting area on the website? Will there be times in which that bay will allow 7 yard targets and from the holster? Do any indoor ranges allow from the holster? Not military affiliated.
