Taurus GX4XL — Extended Slide and Barrel Assembly By: Stephanie Kimmell


The second iteration of the popular Taurus GX4 micro-compact pistol 9mm pistol is now on the scene. The GX4XL features a longer slide and barrel configuration for a boost in accuracy and terminal performance. Two slide options are available, standard and optic-ready, and the gun ships with two magazines.

As described by Taurus:

The GX4XL is built on the same award-winning polymer receiver as the GX4. Hailed for its exceptional handling characteristics in a micro-compact profile, the GX4XL’s hybrid stainless steel and polymer receiver includes a modular grip with standard or high-swell backstrap options for a custom fit, industry-leading grip texturing for optimal firearm control, an ergonomic and reversible magazine release to promote no-fumble mag swaps, and a class-leading flat-face target trigger with a generous trigger guard to accommodate all hand sizes.

What separates the GX4XL from the GX4 is its extended barrel and slide assembly. The GX4XL barrel is .64 inches longer than that of the GX4. This extended length translates to an increase in muzzle velocity and harder hits downrange. With this increased barrel length comes a longer slide profile and subsequent extended sight radius. Already noted for its remarkable accuracy, the GX4XL further tightens the point-of-aim/point-of-impact ratio. In short, the deep-conceal GX4XL’s micro-compact design gives up nothing in the kind of terminal performance, accuracy, and handling serious EDC practitioners demand.

Taurus GX4XL Magazines

The GX4XL ships with two magazines—one 11-round and one extended 13-round magazine in both standard and T.O.R.O. slide configurations. For capacity-restricted states, the gun ships with two 10-round magazines in both configurations. All feature magazine and grip cuts to aid in magazine stripping, if necessary.

As with the GX4, the GX4XL comes with a serrated blackout steel drift-adjustable rear sight and a fixed white dot front sight. The rear sight dovetail cut and front sight mounting hole are compatible with that of common aftermarket sight systems, making tritium night sights an upgrade option.


Taurus offers the GX4XL with the T.O.R.O. (Taurus Optic Ready Option) slide for shooters who want to mount a micro red dot sight to the GX4XL. The T.O.R.O. slide has a direct-thread mounting system (no plate) that works with common micro red dots:

  • Shield RMSc
  • Holosun HS507K X2
  • Sightmark Mini Shot A-Spec M3
  • Trijicon RMR cc Red Dot (with adapter plate P/N: 10028170)


The GX4XL carbon steel slide is treated with a gas nitride finish for enhanced surface hardness and to reduce wear. The stainless-steel barrel is DLC (Diamond-Like Carbon) coated for reduced friction and resistance to wear and corrosion. Taurus advises,  “Not only does the Diamond-Like Coating boost surface durability, the coating’s inherent lubricity also reduces friction for smooth, reliable operation in the most austere conditions.”


The GX4XL ships with two backstraps: standard and high-swell. The standard backstrap has a slight palm swell. Users who prefer a higher wrist position for natural point-of-aim can swap it out for the high swell backstrap.
