The installed steel iron sights are co-witness height for use with a mounted MRD, and the slide includes front and rear serrations. A loaded-chamber witness hole in the barrel hood is visible through the ejection port.
The 4.1 in non-threaded barrel is cold hammer-forged with a recessed crown and polished feed ramp. This build emphasizes durability and smooth feeding, with a 1:16 RH twist optimized for 10mm projectiles.
Ergonomics are set up for a wide range of shooters: the pistol includes interchangeable backstraps with aggressive texturing and fully ambidextrous controls, including the slide stop and ambidextrous push-button magazine release. A MIL-STD-1913 accessory rail on the frame supports common weapon-mounted lights or accessories.
