Overview
Designed to support faster, more certain magazine insertion, this enhanced mag well is aimed at shooters who want a cleaner reload interface on compatible Gen 4 Glock pistols. It fits Gen 4 versions of the G17, G22, G31, G34, G35, and G37, and works with Magpul, OEM, and most aftermarket magazine floor plates, along with many common magazine extensions. There are fit considerations to note: some reduced-capacity 10-round factory magazines and some large aftermarket floorplates may interfere, and it is not compatible as delivered with optional factory Glock Modular Back Straps. For hunters and range users who run a compatible setup and want added reload consistency, it offers a practical upgrade with clear compatibility limits.
