Test: SIG Sauer 1911 STX Two-Tone pistol with .45 ACP

The SIG Sauer 1911 STX Two-Tone found its way to Germany from Exeter, US. Its eye-catching appearance is mainly thanks to the Two-Tone color design. The steel slide is black and forms a contrast to the light-colored stainless steel frame. The design is rounded out by strikingly grained maple grip panels with the company logo. Besides the typical SIG edge, the slide also has wide, undulated repeating grooves in the back. The cartridge extractor is located on the outside of the robust slide lock. The barrel has a classic bushing in the front.

While the slide has an extravagant flair, the frame has a very normal appearance. It comes with a flat mainspring, a beavertail with a memory groove, and checkering on the front and back of the grip. The short wing safety is located on both sides. The trigger and hammer are skeletonized.

The magazine well funnel that is screwed on in front of the magazine well simplifies reloading. As was already the case with the Stainless Target, the interior mechanism has a short guide rod in addition to a spring and the corresponding guide bushing. The rampless barrel is attached to the top of the slide lock by means of two ridges.

The beavertail of the SIG Sauer 1911 STX Two-Tone pistol also eliminates the possibility of the hammer biting the shooter.

The SIG Sauer 1911 STX can be taken apart even without a bushing wrench. The guide bushing can be pushed in easily by hand.

All of the controls are in their normal positions on this government frame. The switching elements all click neatly into place. Only the tension grooves on the hammer surface are a little too slippery (–1 point). There were no special incidents or deductions in the safety evaluation (–0 points).

The SIG Sauer 1911 STX Two-Tone does not cause any interference and all of the safety elements work reliably. The evaluation of the classic 1911 frame in the trigger grip design yielded no deductions (–0 points). The well-formed grip angle and the checkering on the front and back of the grip are appealing. While the wooden grip panels look very attractive with their grain, the surface is as smooth as glass and therefore offers very little grip.

The trigger creeps a few millimeters, but then at least achieves almost dry trigger action. The trigger weight is around 2,300 grams, though still a little too high (–3 points). The aluminum trigger also has an adjustable trigger stop.

The SIG Sauer STX comes with driftable steel sights that have three white dot inserts. The sight grooves have been kept very narrow. Even though they are not fully adjustable sport sights, the sights suit the firearm very well (–0 points).

There are a few deductions in the workmanship test section (–3 points). For one thing, the slide lock sits on the slide with very little play, especially in the front area. And for another, there are noticeable manufacture traces in the undulated repeating grooves of the slide. However, the frame, the inner workings and all of the controls look cleanly manufactured.

In the precision test, the pistol proved that it shoots well despite the play between the frame and the slide. The SIG Sauer 1911 STX Two-Tone punched its closest shot group in the test paper using Remington cartridges. Its best score is with 45-millimeter ammunition. It therefore scores 47 points in this evaluation (–3 points).

Test Conclusion for the SIG Sauer 1911 STX Two-Tone Pistol

The SIG Sauer 1911 STX Two-Tone stands out thanks to its unique design. The attractive maple grip panels and the two-tone exterior give the firearm its own distinctive look. When it comes to accessories, the STX proves to be more universal.

This firearm is not suitable for hard sport use, due to the lack of adjustable sights and the stiffness of its trigger ex works. However, it offers skeletonized components, a magazine well and good precision right from the start. The STX comes with two magazines, operating instructions in color and a lockable SIG Sauer case.
