HK45 Nickel-Plated Sear Spring

The Heckler & Koch Sear Spring (H&K part no. 215691) is a genuine factory replacement part for the HK45 pistol, finished with a nickel plating that resists corrosion in the small internal channel where it rides. The sear spring provides the tension that lets the sear reset properly after each trigger pull, so a fatigued or corroded original is a common source of inconsistent trigger feel.

Key Specifications

• nickel-plated finish resists corrosion inside the fire-control channel where the spring rides.
• factory H&K replacement part for the HK45 pistol, matching original fit and tension.
