Capacity is 17+1 with the included magazines, and the pistol operates on a semi-automatic, striker-fired action. A flat-faced trigger and the absence of an external manual thumb safety define the control layout.
The slide is optics-ready via a factory optic cut and removable cover plate. Factory sights include a SIG XRAY3 green dot front and a steel rear notch.
The polymer grip module uses aggressive molded texturing for purchase and accepts interchangeable backstraps for fit adjustments. A true M1913 Picatinny accessory rail with three slots supports common rail-mounted accessories. Country of origin is USA.
