Nighthawk Custom 1911 Sear, Fully Machined

The Nighthawk Custom 1911 Fully Machined Sear (Nighthawk part no. SP0350-1) is cut from solid tool steel rather than pressed from metal-injection-molded (MIM) powder, giving it a harder, more consistent engagement surface where it contacts the hammer hooks. The sear is one of the most trigger-feel-critical parts in a 1911’s fire control group, since its engagement geometry with the hammer directly determines pull weight, creep, and how crisp the final break feels. Nighthawk Custom machines this sear to the same tolerances used across its custom 1911 builds, giving gunsmiths a precision starting point for a professional trigger job rather than a cast or MIM part that may need more hand-fitting to true up. A fully machined sear is generally more durable over high round counts than a cast equivalent.

Key Specifications

• It is fully machined from tool steel rather than cast or MIM.
• It is built to match-grade tolerances for consistent hammer engagement.

Frequently Asked Questions

Why choose a fully machined sear over a MIM part? A fully machined sear offers a harder, more consistent engagement surface and is generally more durable over high round counts than a cast or MIM equivalent.

Does the sear affect trigger feel? Yes, the sear’s engagement geometry with the hammer hooks directly determines pull weight, creep, and how crisp the trigger break feels.
