Description
The sear is the heart of any good 1911 trigger job, and Nighthawk Custom built this one to be the part a serious build deserves. It's part of their Fully Machined line, which means it's CNC machined from a solid 11L17 carbon steel billet and then hardened, never cast or metal injection molded. That distinction matters. Bar stock parts hold their geometry under wear far better than MIM, which is exactly what you want from the component that controls hammer engagement and trigger feel.
What makes this one easy to like is that the primary and secondary hammer engagement surfaces come pre-cut and polished from the factory. Plenty of folks report a great trigger pull straight out of the package with minimal touch-up. If you're chasing a specific pull weight or a glass-rod crisp break, those same clean factory cuts give your gunsmith a dialed-in starting point to stone the angles exactly where they want them. The hardening helps it stay put once it's set, so your trigger feel won't drift after a few thousand rounds.
Fitment covers the standard 1911 family, including Government, Commander, and Officers frames. Keep in mind this is a fitted part, not a true drop-in. The sear and hammer relationship is what keeps the gun safe and reliable, and a botched job can cause hammer follow, where the hammer won't stay cocked. If you're not comfortable with a sear jig and stones, hand it to a competent 1911 gunsmith and let them set the angles.
This sear is a smart pick for anyone building or upgrading a 1911 who wants a quality fire control part without paying for an out-of-spec MIM piece. It's also a solid replacement if you've chewed up a sear tip or want to refresh an older trigger group. You get one Nighthawk Custom Fully Machined carbon steel sear. Pair it with a matched hammer and a fresh sear spring and you've got the foundation for one of the best triggers in the handgun world.

Frequently Asked Questions
Is this sear drop-in or does it need fitting?
It comes with the primary and secondary surfaces pre-cut and polished, so many people get a good trigger right away with minimal touch-up. That said, it's a fitted part, not guaranteed drop-in. For proper function and safety, plan on fitting it to your specific hammer and frame, or have a 1911 gunsmith do it.
What is the sear made of?
It's fully machined from a solid 11L17 carbon steel billet and then hardened. Bar stock construction holds tighter tolerances and resists wear far better than cast or MIM parts, which is exactly what you want from the component that controls your hammer engagement and trigger pull.
Will this fit my 1911?
It's built for the standard 1911 platform and works across Government, Commander, and Officers size frames. As with any quality fire control part, frames vary slightly, so final fitting to your gun's hammer hooks is part of the install.
Do I need special tools to install it?
To fit and stone the angles correctly you'll want a sear jig, like an Ed Brown or Marvel, along with a medium and a fine stone. If you don't have those tools or experience, it's worth letting a gunsmith handle it, since an overdone sear can cause hammer follow and an unsafe gun.
Why upgrade to a Nighthawk sear over a factory one?
Most factory sears are MIM, which can be inconsistent and wear over time. This Nighthawk Custom sear is machined from solid steel and hardened, giving you cleaner geometry, a crisper break, and a part that holds its trigger feel through high round counts.
