For anyone carrying with a Safariland ALS holster, this little guard is a smart add-on for extra safety. The 6006-1 fits models 6377, 6378, and 6379 (and can be retrofitted to other ALS holsters without the SLS system). It's a simple cover that goes over the ALS lever, preventing accidental or unauthorized release of your firearm. That's especially important in crowded spaces or if you have curious kids around. The guard is easy to install—just attach it to your existing holster without any major modifications. It adds a layer of security without interfering with your draw when you intend to use it. Made by Safariland, so you know it's built to their tough standards. If you value retention and safety, this accessory is a no-brainer. Keep your gear secure and your mind at ease.
