Elite Tactical\'s 30 round mag is made to fit all .40 Cal Glock pistols including G22, G23, G24, G35 and G27. Clear Black - GLK-22-210 - E.T.S. magazines are made from advanced polymers that provide extreme impact resistance so they won't crack or break when dropped. The translucent smoke polymer allows for viewing of ammo type and count. With superior temperature tolerances, these 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.
