Glock OEM Glock 20 10MM 15 Round Magazine - Cardboard Style Packaging, Black - MF20015 / 2015 - 764503200151
Product Description
Running high-power 10mm Auto loads through hard-use handguns requires maximum magazine spring tension, feed lip rigidity, and flawless follower alignment to prevent harsh recoil-induced feeding failures. Aftermarket or worn magazines often suffer from feed-lip spreading and failure-to-feed errors under the heavy shock of full-power 10mm ammunition. The Glock OEM Glock 20 10mm 15-Round Factory Magazine (MF20015 / 2015) resolves feeding reliability and durability constraints by featuring Glock's legendary steel-reinforced polymer construction built directly to original factory specifications.
Constructed around a hardened steel inner lining encapsulated by Glock's proprietary high-impact black polymer, the MF20015 magazine resists swelling, drop damage, and thermal distortion. The heat-treated internal steel spring drives a high-visibility anti-tilt polymer follower, ensuring smooth upward round presentation whether feeding light target loads or heavy hard-cast bear defense ammunition. Rear-facing witness holes allow armorers and shooters to quickly verify remaining round count at a glance.
Designed for full cross-generation compatibility, this OEM factory magazine features dual ambidextrous mag-catch cutouts, making it seamlessly compatible with Gen 3, Gen 4, and Gen 5 Glock 20 series handguns (including G20, G20SF, and G40 10mm models). Ships in official factory cardboard/clamshell retail packaging for guaranteed factory authenticity.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment & Model Compatibility Matrix: Fits standard Glock 20 (Gen 3, Gen 4, Gen 5), Glock 20SF, Glock 40 Long Slide, and Glock 29 10mm Handguns (extends past grip on G29). Also compatible with 10mm PCCs and carbines accepting standard Glock 20 magazines. Cross-Generation Note: Features dual cutouts for left- or right-handed reversible magazine releases.
Loading & Staging Guidance:
- Safety check the firearm: clear chamber, remove active magazine, and physically/visually inspect magazine well.
- For initial loading of new factory 10mm magazines, use a Glock mag loader tool to depress the stiff internal spring during the final 3–4 rounds.
- Load 10mm Auto rounds flat against the rear spine of the magazine body to ensure full seating against the witness holes.
- Insert magazine firmly into the magazine well until the magazine catch engages with a distinct tactile click.
- Keep magazine bodies free of heavy lubricants internally to prevent oil accumulation from attracting dirt or unburned powder residue.
