The Warne Mounts Magazine Ext, Glock 43X/48, +4 Black is a precision-machined aluminum magazine extension designed to add four additional rounds of 9mm Luger capacity to your factory Glock 43X or 48 magazine. Built from durable 6061-T6 aluminum with a hardcoat anodized black finish, it offers a clean profile that complements the slimline Glock frame while maintaining reliable feeding.

This extension is ideal for shooters who want extra capacity for range sessions, training, or everyday carry while retaining the familiar feel of their Glock 43X or 48. Its contoured shape is engineered to aid magazine insertion and provides subtle finger grooves that help you strip the magazine from the pistol if needed. Backed by Warne Mounts’ reputation for solid machining and thoughtful design, this mag extension is a straightforward upgrade for your Glock slimline platform.
