The DR920 Combat Optic balances durability and shootability with its 17-4 stainless slide and match-grade 416R stainless barrel. The barrel is unthreaded with a flush crown, emphasizing reliability and consistent accuracy in a duty-length configuration.
The slide incorporates front and rear directional serrations and an optic cut with a cover plate. Its multi-footprint direct-mount interface allows low, strong mounting of compatible pistol optics, and the factory sight setup is intended for a lower-third co-witness with many mounted optics.
The black polymer frame is shaped for control, featuring an extended beavertail, a double undercut trigger guard, and molded recoil-control ledges. Interchangeable backstraps (NPOA system) let the shooter tailor the grip to preference, and a flared magazine well funnel speeds reloads.
Duty-focused details include a flat-faced aluminum trigger with a trigger safety, a 17-round capacity, and an integral accessory rail on the dustcover. The pistol is compatible with most Glock 17 holsters and carries MADE IN USA markings from Shadow Systems in Plano, Texas.
