Good to see some LV people here. I work at/shoot at the CCSC, usually in the Rifle/Pistol tower or on the Pistol line. We are currently looking for some good RSO's for the rifle/pistol range. If you have any questions or need any help with anything at CCSC, please feel free to message.
JJ is a great instructor, and is very passionate about teaching people to be better. I was fortunate to get to know him a bit while he was up in Alaska teaching a few classes and competing in a match. He also built my USPSA gun.
If you are willing to travel a few hours, that opens up your options a bit as well. Presscheck is doing a pistol class in San Diego in June for example.
I just took the Greenline tactical class north of LA as well, and was worth my two hour drive.
A large part of it will be driven by what kind of training you are seeking out.
