Glock Oem Mag Catch Rev G21 Gen4

The Glock Oem Mag Catch Rev G21 Gen4 is a critical factory replacement component designed for operators who demand unwavering reliability from their duty sidearms. Whether you are maintaining a high-round-count training pistol or restoring a service weapon to factory specifications, using authentic components ensures the magazine remains seated under heavy recoil. This specific magazine catch is engineered for the Generation 4 platform, accommodating the unique frame geometry and ambidextrous capabilities required by modern professional shooters.

Constructed from high-strength polymer to match the Glock frame's durability, this component features the reversible design characteristic of the Gen4 series. The internal geometry is precision-molded to interface perfectly with the notches on Glock 21 magazines, preventing accidental drops while facilitating smooth, rapid reloads during high-stress engagements. At a weight of only 0.06 lbs, it maintains the lightweight profile of the firearm without compromising the structural integrity of the magazine retention system.

This mag catch is essential for left-handed shooters or those who prefer a customized control layout, as it allows for reversible installation on either side of the frame. It is compatible exclusively with the Glock 21 Gen4 chambered in .45 ACP, providing a drop-in fit that requires no permanent modification to the receiver. For professionals looking to buy authentic parts for a duty-ready setup, this OEM component is the standard for maintaining the firearm's original performance and safety ratings.
