Nighthawk Custom 1911 Drop-In Trigger System – Stainless Steel

From Nighthawk’s website:

An all-in-one unit, the DTS replaces your existing hammer, hammer strut, sear, disconnector, and sear spring. Your existing sear pin and hammer pin will be retained for use with the DTS, but no other parts are necessary for installation. With a steel housing securing the unit, the DTS features all Fully Machined™, stainless steel internal components. The traditional three-pronged sear spring is no longer necessary as the springs for the disconnector and sear are built into the unit. A single-leg grip safety spring is included with the DTS to replace the existing sear spring. We designed the Drop-In Trigger System to be approximately 3.75-4 lb trigger pull in most applications after the proper break-in period.
