Warne 3126 Magazine Extension Glock 19/23 6061-T6 Aluminum Black - +5rd 9mm Luger / +4rd .40 S&W

The Warne 3126 Magazine Extension is a precision-machined base pad designed to extend factory Glock 19 and Glock 23 pistol magazines. Precision-machined from 6061-T6 aluminum and finished in a durable hardcoat anodized black, this extension replaces the factory base plate to add +5 rounds of 9mm Luger capacity or +4 rounds of .40 S&W capacity, depending on the magazine it is installed on.

Engineered to tight tolerances, the 3126 installs onto standard Glock 19 and Glock 23 magazines for a precise fit that maintains smooth magazine insertion and reliable function. The hardcoat anodized surface resists wear and corrosion from daily carry, range sessions, or duty use, while the extended footprint gives the shooter a positive purchase surface for faster, more consistent magazine changes. The design also improves overall handling and control of the magazine during reloads.

Warne applies the same precision machining quality found across its broader accessory line to this magazine extension. The 3126 is a straightforward, no-magazine-replacement upgrade for Glock 19 and Glock 23 shooters looking to add round count while retaining their factory magazines.
