Shield Arms G19ME5BLK +5 Magazine Extension Glock 19/23 9mm 40SW

The Shield Arms G19ME5BLK Magazine Extension transforms standard Glock 19 and 23 magazines into higher-capacity solutions without compromising reliability. This precision-engineered extension adds 5 additional rounds to factory magazines, increasing capacity to 20 rounds for 9mm and .40 S&W configurations.

What Makes This Different

Unlike polymer alternatives that can crack under stress, this extension features black anodized aluminum construction that withstands repeated use and environmental exposure. The machined aluminum body provides consistent spring compression and maintains proper magazine geometry for reliable feeding. Shield Arms designed this extension with reinforced mounting points that distribute stress evenly across the magazine tube.
