Glock 20 15-Round Magazine

Factory 10mm Glock Magazine

This is Glock's own 15-round magazine for the Glock 20, the full-size pistol chambered in 10mm Auto. It is factory OEM, meaning Glock made it as the original part rather than a third-party copy, so it matches the pistol's feed geometry and catch dimensions exactly. G20 owners use it as a spare for the range, the field or a carry rig, and Glock 29 owners use it as a higher-capacity backup.

Features

• 15-Round Capacity — Holds fifteen rounds of 10mm Auto, the standard full-size capacity for the Glock 20.
• Genuine Glock OEM — Made by Glock to the same specification as the magazines that ship with its pistols.
• Steel-Lined Polymer Body — A hardened steel insert runs inside the polymer shell and holds the magazine's shape under a fully compressed spring.
• Steel Feed Lips — The metal edges at the top, which hold the top round in position until the slide strips it into the chamber, are visible in steel.
• Catch Notches On Both Sides — Cutouts on either side of the body lock onto the magazine catch, including when the release is moved to the opposite side on later generations.
• Flat Polymer Base Plate — A flush, flat floorplate sits low under the grip and can be removed for cleaning.
• Black Finish — Plain black polymer that matches the factory Glock frame.
• Multi-Model Fit — Works in the Glock 20, 20SF, 40 and 29, all of which share the large-frame 10mm magazine.

Fit and Compatibility

The magazine fits Gen 2, Gen 3 and Gen 4 versions of the Glock 20, along with the slimmer-grip 20SF and the long-slide Glock 40. In the subcompact Glock 29 it seats and feeds normally but extends below the shorter grip, which many owners accept for the extra rounds in a reload. The manufacturer part number is MF20015.
