Magpul MAG932-BLK GL Enhanced Mag Well Compatible w/Gen4 Glock 17/22/31/34/35/37 Black Polymer

The Magpul GL Enhanced Magazine Well is engineered to provide reliable, positive magazine insertion when it matters most. It fits Gen4 Glock 17/22/31/34/35/37 and works with Magpul, OEM, and most aftermarket magazine floor plates, as well as most common aftermarket magazine extensions. Note that recent generations of reduced capacity 10rd factory Glock magazines feature dimensional differences that may interfere with the Magpul GL Enhanced Magazine Well, and some large aftermarket floor plates may also cause interference. The Magpul GL Enhanced Magazine Well for Glock 17 Gen4 and Glock 19 Gen4 are not compatible as delivered out of the box with optional factory Glock Modular Back Straps. While end user modification is minor and may be attempted, it is taken at own risk.
