The ergonomic grip system uses interchangeable backstraps and side panels for a customized fit. Controls, slide release and magazine release, are fully ambidextrous. The DA/SA trigger offers a double-action pull and a single-action break. Glow-in-the-dark sights and a Picatinny rail round out the feature set.
