Special Features

• The cold-hammer forged polygonal barrel delivers tighter bore-to-bullet contact than conventional cut-rifled barrels, extending barrel service life and maximizing velocity consistency with each round fired.
• An HK proprietary O-ring at the barrel muzzle creates a precision-fit lockup between the barrel and slide, tightening tolerances for improved shot-to-shot accuracy.
• The threaded barrel ships with a thread protector and is cut to M16x1 LH pitch, making it directly compatible with a wide range of suppressors and muzzle devices.
• Adjustable suppressor-height sights are co-witnessed for use with or without a suppressor, so the sight picture remains usable regardless of muzzle device configuration.
• The integral MIL-STD-1913 Picatinny rail accepts standard weapon lights and laser aiming devices without requiring an adapter.
• Two interchangeable backstraps ship with each pistol, allowing the shooter to fine-tune grip circumference to fit their hand without modifications or added cost.
• The DA/SA V1 trigger system gives the shooter a deliberate double-action first pull followed by a lighter, more precise single-action pull for follow-up shots.
