Left hand stocks are available, but the top lever still opens to the right, so "the gun" itself is still a right hander. But yes it will fit a left hander. Being pedantic, but clear.
Custom stocks are available from the factory by sending them your dimensions and paying the appropriate fee, which is actually fairly reasonable. What you need is someone to measure you up and get your dimensions in the first place.
Contact CGUSA directly, they'll be able to sort it out for you.
Wes at CGUSA usually has a few stocks with cast on in stock. Best to call him about availability. If you are buying new they can fit a left handed stock to a gun in inventory and send it to your retailer. There is an upcharge for the left handed stock, but its well worth it from a shooting stand point.
