Built to exceptionally tight tolerances, the STI Tactical 4.0 offers custom-grade enhancements, a double-stack frame and top-notch accuracy.

As a full-time patrol officer, I’ve carried STI’s Tactical 4.15 pistol both on and off-duty for the past five years, so I’ve definitely developed an affinity for the Texas-based company. The Tactical has proven to be rugged and reliable for me on duty, with above-average features and utility. If you haven’t fired one of STI’s pistols built on the company’s modular 2011 frame, I suggest you give it a try. It’s far leaner in the grip area than one would expect for a pistol with such a magazine capacity. I’ve even had Glock shooters remark that the grip circumference was less than they’d expected.

It’s only natural then that I keep my ear to the ground for new developments from my friends at STI, not only in the Tactical line of pistols, but throughout the various other offerings from the firm.

STI has added a few models to the Tactical line, and what was once known as the Tactical 4.15 has been changed to the STI Tactical 4.0, which I think was intended to simplify the models, as the dimensions have remained the same. New also is the Tactical 3.0 model, which features the same 2011 grip frame and capacity, albeit with a 3.75-inch barrel.

At the heart of the Tactical 4.0 is its 4.26-inch bull barrel, made from a 416R rifle-grade stainless steel forging that is ramped and fully supported. It has button-broached rifling with a 1-in-16-inch twist rate, and the crown is cut at a 45-degree angle.

The slide is machined from 4140 carbon steel, and it has deeply cut cocking serrations at the rear, a flat top and a slight bevel up front. The ejection port is lowered and flared. For aiming, the Tactical 4.0 has an STI ramped front blade and a fixed Novak-style rear sight. Both are serrated. However, I ordered my test pistol with a fiber-optic front
and STI’s own Tactical Adjustable Sight (TAS) rear with tritium. The tritium is installed in the configuration of a hori-zontal bar under the notch of the sight. Two-dot night sights are also optional.
