Taurus Gx4 Tau 1-Gx4M931B 9Mm Bk/Pvd Blue 3.0 11/13R
The Taurus GX4 Tau is a compact 9mm striker-fired pistol built for shooters who want reliability and shootability in a carry-friendly package. With a 3-inch barrel and overall length under 6.1 inches, it's slim enough for everyday carry or backup duty without sacrificing the ergonomics and controls that matter when you need to shoot fast and straight. The GX4 Tau bridges the gap between pocket guns and full-size duty pistols—it's at home at the range, in the field, or riding daily.
The trigger is what sets this one apart. A flat-face design with a crisp break and short reset makes follow-up shots intuitive and controllable, whether you're working on accuracy drills or defensive transitions. The included adjustable rear sight (serrated, drift-adjustable) and fixed front sight get you on target quickly if you're not running optics; the sight plane is designed for natural point-of-aim. Two backstrap options—standard and high-swell—let you dial in the grip angle that works for your hand and shooting style, which makes a real difference in a compact pistol.
Durability and corrosion resistance are engineered in. The slide is carbon steel with a gas nitride coating for surface hardness; the barrel wears a black DLC finish that resists wear and corrosion. Disassembly is straightforward thanks to an easy takedown pin, so field cleaning is simple. You get two magazines in the box—an 11-rounder and a 13-rounder—giving you options depending on how you carry or what mission you're suited up for.
The GX4 Tau runs on a dual-safety system: a trigger safety and a striker block. The stainless steel frame insert keeps things solid where it counts. At 18.5 ounces unloaded, it's light enough to carry all day without fatigue, but substantial enough to manage recoil and stay controllable through rapid fire.
