The slide is factory cut for micro optics and supports the RMSc and Holosun K footprint. This gives the pistol a low-profile mounting interface while keeping the Slimline form factor intact.
Custom touches include a flat-faced aftermarket trigger shoe for a straight press, a Trijicon front sight with a high-visibility orange outline paired with a plain rear notch, and aggressive grip texture panels with Grit Grips branding on the frame.
The pistol uses a black polymer Slimline frame with front and rear slide serrations and a 3.41 in steel barrel. It is striker-fired with a trigger safety and fixed iron sights.
Slide and barrel are marked AUSTRIA/AT and carry Austrian proof marks. Included magazines comprise Glock-marked slimline polymer mags and steel-bodied aftermarket 43X-pattern mags, providing a supplied capacity configuration of 15+1 with the included set.
