Hi Gerald, it means the manufacturer paid Dictator Newsome the $200 extortion fee to have it put on the CA approved handgun roster.
Stay safe & have a great day!

Hi Gerald and welcome. It simply means a manufacturer has submitted a model to California for testing, paid said fees and if approved, it is added to the CA DOJ Handgun Roster. It is then available for purchase by CA residents. CA DOH Handgun Roster is here: https://oag.ca.gov/firearms/certified-handguns/search?make=All ----------- Cheers and stay safe!

Good morning to you!! It means the firearm meets certain requirements for the state of California. Please see attached for more information.
