Description
This ignition kit brings together all the critical fire control components you need for a serious 1911 trigger upgrade. The stainless steel lightened hammer is the centerpiece of the build, delivering faster lock time through its skeletonized design while maintaining the strength and reliability you demand. Every part in this kit is precision-machined from solid tool steel, eliminating the micro-porosity and tolerance issues you get from factory MIM components.
What's Inside the Ignition Kit
The kit includes everything for a complete trigger job: the HD hard sear, ball head disconnector, evolved sear spring, and a 19lb ISMI mainspring. These aren't generic parts thrown together. The hard sear provides precise hammer engagement, the ball head disconnector ensures smooth resets, and the mainspring is calibrated to work well with common suppressor safety systems. Together, they create the foundation for that clean, crisp break that separates a quality trigger from a factory pull.
This isn't a drop-in kit, so you'll want a qualified gunsmith to fit everything properly. The hammer hooks and sear face need to be matched, and the sear spring will require tuning for your specific setup. If you run suppressors on your pistols or are looking to upgrade a Springfield Prodigy, this kit was built with your platform in mind. The 19lb mainspring spec works well with throw-away style safeties, letting you keep that integral safety while maintaining a lighter, more predictable pull.
Hammer Quality and Performance
The lightened stainless hammer is fully machined from solid stainless steel using a single machine hold that keeps tolerances within .0005 inches. This precision approach means all the critical dimensions line up perfectly for that flawless trigger job. The reduced weight (10.7 grams) cuts lock time noticeably compared to factory hammers, and the stainless finish resists corrosion while matching other stainless components in your build. If you're building a custom 1911 or upgrading an existing one, this hammer delivers the performance and durability that competition and duty pistols depend on.

Frequently Asked Questions
Will this kit work with my Springfield Prodigy?
Yes, this kit works great on the Prodigy, but make sure you get the version with the shortened sear specifically designed for that platform. The standard sear can cause hammer follow issues on a Prodigy. If you're looking at this particular model, confirm it's the Prodigy-specific variant before ordering.
Is this a drop-in kit?
No, this kit requires professional gunsmith fitting. The hammer hooks and sear face need to be matched through careful stoning, and the sear spring will need tuning for your gun. Trying to force it without proper fitting can result in safety issues and poor trigger performance. Plan on taking it to someone experienced with 1911 fire control work.
What's the advantage of the lightened hammer?
The reduced weight and skeletonized design lower the hammer's rotational mass, which means faster lock time and quicker ignition. Combined with the precision hard sear in this kit, you get a noticeably crisper break and better consistency shot to shot. The stainless construction also gives you corrosion resistance and durability that beats factory components.
Can I coat the hammer after installation?
Avoid coatings that require heat during application, as they can cause brittleness and potentially fracture the hammer. Coatings like Robar's NP3 that don't require heating work fine, but check with your coater first to make sure their process is safe for heat-treated stainless steel parts.
