Firearm modifications

Modifications are allowed for approved CCW listed firearms so long as all parts/modifications are legal in the State of California. All firearm modifications must be inspected at the time of training to ensure the firearm is in safe working order.

  • If a modification(s) is done after the issuance of the license, you must complete the training/inspection as if it were a newly listed firearm. The training certificate should be emailed to to be added to your file.
  • The responsibility for the legality of a firearm and its parts/accessories lies solely with the owner/applicant.
  • Any violations or failure to adhere to state laws/regulations will result in immediate suspension and/or revocation of a license.
