Extended Magazine Well — Glock 17 Gen4 — Magpul®

Faster reloads, refined ergonomics

The Magpul^® extended magazine well for Glock 17 Gen4 improves magazine guidance and speeds reloads under stress. The low-profile flare helps funnel magazines into the grip more reliably during rapid transitions, making it a valuable upgrade for competition, training and dynamic shooting.

Reinforced polymer construction

Manufactured from a reinforced, impact-resistant polymer, this magwell is engineered to withstand hard use while keeping added weight to a minimum. The robust construction delivers long service life and a clean, factory-integrated appearance on the Glock 17 Gen4 frame.

Improved handling and integration

The flared geometry provides a consistent tactile reference for the support hand and improves purchase on the grip during reloads. The magwell is shaped to follow the Glock 17 Gen4 contour for a seamless fit while maintaining a concealable profile.

Installation & compatibility

Designed for Glock 17 Gen4 frames; installation is typically straightforward on standard Gen4 pistols. Some aftermarket frames, backstraps or accessory-ready frames may require minor fitting. Installing a magwell can affect holster fit and concealment — verify holster compatibility after fitting and test function before operational use.
