Increase your firepower potential without blasting a hole in your budget with this after-market quality constructed magazine from Red, White, and Blue. The magazine is constructed of black Zytel polymer just like the factory magazine. It has a metal liner to prevent wear on the pistol’s magazine release, like the factory magazine. This magazine will extend approximately 6″ below the grip.
This Zytel magazine has small holes to reveal the number of rounds left. These are brand-new magazines and as such, the springs are tight, so loading the first few rounds may require a loader/unloader tool.
The 31 round extended magazine will fit Glock handguns that are using existing Glock barrels or .40 barrels in existing Glock gun. These are Pre-Ban and fit all .40 Cal Glock 22, 23, and 27.
