Pro-Lok works very hard to design and provide quality firearm safety devices.  Equally important is providing our customers with the very best customer service available.  We are proud of the reputation that we have built. Pro-Lok has worked in conjunction with the California Department of Justice and the ASTM in helping set standards for firearm safety.  We have also worked with federal, state, and local law enforcement agencies, major firearm manufacturers, and non-profit organizations in providing firearm safety products.  All of our firearm safety products are in compliance with the California Department of Justice Standards.
