Unique Hop-Up Adjustment: The hop-up can be fine-tuned with up to 120 settings using a special tool conveniently stored within the backstrap of the grip and inserted through the muzzle, eliminating the need to disassemble the slide during gameplay.
Ambidextrous Controls: The design includes fully ambidextrous slide release and magazine release controls, making it user-friendly for both left- and right-handed shooters.
Ergonomic Design: The pistol has a textured grip and comes with interchangeable backstraps to fit different hand sizes, enhancing comfort and handling.
Durable Build: It features a combination of a lightweight polymer frame and a machined metal slide with venting ports, offering both durability and agile handling.
Accessory Compatibility: A 20mm (or 22mm) Picatinny accessory rail is integrated into the frame for mounting lights or lasers, and the outer barrel has a 12mm CCW thread for attaching suppressors or tracer units.
