It appears to list all of the CA approved locks. You will have to call each manufacturer to locate a retailer. But this would be a good cross check to make sure the one you choose is in fact CA approved.
oicw, it is my understanding that you can use any 'CA approved' lock on any gun that it will fit.
However, if you are unsure, you should call your FFL dealer (they will be the ones that won't transfer the gun to you if you do not have a 'CA approved' lock-they also are required to certify you had one at the time of transfer) or in this case call Master Lock at 1-800-558-8892, Customer Service.
Be sure to save the sales reciept (describing the lock purchase) and the packaging so you can prove to the dealer you purchased it within 30 days of the gun transfer--requirement of CA law.
