GX4 vs. GX4 XL: Which Should You Choose?

The GX4XL adds a longer slide and barrel to the GX4 design. Taurus says the longer slide adds 1 inch of length compared to the GX4, which increases sight radius and muzzle velocity. The XL barrel measures 3.71 inches against 3.06 inches on the standard GX4. Taurus lists the same 4.40-inch height and 1.08-inch width for both pistols.

The standard GX4 suits buyers who want the shortest overall length for concealed carry. The GX4XL suits buyers who shoot regularly and want the longer sight radius. The GX4XL comes with a standard backstrap and an included high-swell backstrap, so you can adjust wrist position.

GX4 and GX4 XL Specs: Size, Weight, and Capacity

Taurus lists the standard GX4 at 6.05 inches long and 18.70 ounces unloaded. The GX4XL is 6.43 inches long and 20.00 ounces unloaded. Both are single-action striker-fired pistols with a stainless steel frame, an alloy steel slide, a 1:10 right-hand twist barrel, and a Picatinny rail.

Capacity depends on the version. Taurus lists the standard GX4 at 11 rounds, with 10-round versions also available. The standard GX4XL holds 10 rounds, and the GX4XL T.O.R.O. is offered with 11- or 13-round magazines.

GX4 T.O.R.O.: The Optics-Ready Configuration

T.O.R.O. stands for Taurus Optic Ready Option. The GX4 T.O.R.O. has a factory optic-cut slide designed for several popular micro red dot sights, and it includes a flush-mount slide cover plate for use without an optic. Taurus lists GX4 T.O.R.O. versions with 10 and 11 rounds, and the pistol keeps the standard GX4 dimensions and 3.06-inch barrel. Browse red dot sights to pair with it.

GX4XL T.O.R.O.: Longer Slide With an Optic Cut

The GX4XL T.O.R.O. combines the 3.71-inch barrel with a direct-thread, no-plate optic mounting system. Taurus lists compatibility with the Shield RMSc, Holosun HS507K X2, and Sightmark Mini Shot A-Spec M3 footprints. The Trijicon RMR cc mounts with Taurus adapter plate part number 10028170.
