Warne Magazine Extension 9mm Luger/.40 S&W +5/+4 for Glock 19/23 - Flat Dark Earth

The Warne Magazine Extension is a purpose-built magazine accessory designed to increase the round count of factory Glock 19 and Glock 23 magazines. Machined from durable 6061-T6 aluminum and finished in a rugged hardcoat anodized Flat Dark Earth coating, this extension drops onto existing Glock pistol magazines to provide additional firepower without forcing a magazine change.

For 9mm Luger Glock 19 magazines, the extension adds +5 rounds of capacity. For .40 S&W Glock 23 magazines, it adds +4 rounds. The precision-machined aluminum body threads onto the factory magazine base plate, giving the shooter a positive, secure attachment that holds up under repeated range use.

Warne designed the extension with an ergonomic profile that aids magazine insertion and stripping from the pistol under stress. The hardcoat anodized Flat Dark Earth finish resists wear and corrosion while blending with FDE-equipped Glock pistols and accessories. This is a straightforward upgrade path for Glock owners who want a few extra rounds at the ready without switching to an aftermarket magazine.
