About Us

As of November 1, 2011 the process for obtaining an Oklahoma Permit has changed. The new process is explained here. You can start the application process by going to http://www.dps.state.ok.us/swp/ or by calling 1-877-425-2390. You will no longer contact us. All applications will be submitted to DPS. They will direct the applications appropriately from there.
