Taurus GX4 9mm 13rd Factory Magazine

The 13-round extended GX4 mag is the right primary carry mag for most GX4 owners. The flush 11-round is for deep concealment only — at 11+1 capacity and a two-finger grip on most hands, it gives up too much shootability for the marginal concealment gain. The 13+1 extended adds 2 rounds and a fuller three-finger grip, which materially improves recoil control on a 18.7 oz pistol firing 9mm Luger.

NOT cross-compatible with the G3 / G3c / G3X family. The GX4 magazine pattern is a clean-sheet design separate from the rest of Taurus's polymer line. Within the GX4 line, magazines cross-fit between GX4 (3.06-inch barrel) and GX4XL (3.7-inch barrel) since the grip frames are identical.
