Armscor made use of its team’s significant metal-milling skills and employed a steel chassis clamped inside a two-piece aluminum frame, unlike most striker-fired handguns in this category, which are constructed around injection-molded polymer frames. Although this method is more traditional, the rock island armoury stk100 is not some type of vintage or throwback weapon.

It has a number of characteristics, like as an optics-ready slide, that are now common in tactical and competition pistol designs.

The slide of the stk100 is machined from a billet of 4140 high-carbon steel and Parkerized in matte black. It has been meticulously contoured, beveled, and indented to create a fashionable and modern shape, with chevron cuts running along the top edge slightly beyond the front sight.

The front portion of the slide has seven weight-reduction cuts as well as generously sized front and rear cocking serrations.

A retaining screw that holds the metallic white-dot front sight in place enables it to be taken out and changed with a fiber-optic or night sight.

The slide’s cover plate, which was taken off to fit a Vortex Venom red-dot optic for this review, is machined into the vertically serrated, square-notch rear sight. This implies that an installed optic cannot be used to co-witness the iron sights.

The extractor claw of the slide features an extension that serves as a visible and tactile loaded-chamber indication. Whereas Glock’s slide cover plates are composed of polymer, the rock island armoury stk100’s plate is constructed of anodized aluminum.

Removing the slide from the frame shows a set of inner workings that are shamelessly Glock-compatible, including the G17-style barrel, firing pin, and firing pin safety plunger—but there are two noteworthy differences. The 4.5″ barrel’s rifling is a typical land-and-groove arrangement to permit the employment of unjacketed lead bullets. And the guiding rod is constructed of steel rather than polymer, with a single trapped, flat-wire spring.
