Rule the Range With Color From ETS 

ETS magazines are made from advanced polymers that provide extreme impact resistance so they won't crack or break when dropped. With superior temperature tolerances our magazines won't become brittle over time, even when exposed to harsh environments, chemicals, or extreme cold. Its durable construction eliminates creep so the feed lips and body won't spread when being stored long term, even when fully loaded. These new Glock Magazines provide a top notch alternative to an OEM magazine and available in multiple sizes.
