Cylinder & Slide Ultra Light Trigger Pull Kit

The Cylinder & Slide Ultra Light Trigger Pull Kit is a complete trigger system designed for shooters who demand a crisp, light pull without sacrificing reliability. Built for 1911-style pistols, this kit delivers a 3.5 lb. pull weight—ideal for competitive shooting, precision range work, and shooters who value speed and control. Each component is precision-engineered and tested to function without hand-fitting, so installation is straightforward for gunsmiths and experienced builders.

Cylinder & Slide manufactures these parts using wire EDM cutting from bar stock, followed by honing, polishing, and heat treatment for durability. The ultra-light, skeletonized hammer is relieved to prevent frame contact, while the ultra-light match sear and disconnector are optimized for the specified pull weight. The lightened sear spring works with an 18 lb. hammer spring to deliver the crisp, clean break that competitive shooters expect. Hammer edges are chamfered to reduce slide drag and wear on clothing—a practical detail for carry or competitive use.

This kit includes everything you need: hammer, sear, disconnector, sear spring, and hammer spring. All profiles and through-holes are mechanically correct, so you're not paying for parts that require extensive fitting. If you're building or tuning a 1911 for match shooting or high-volume range time, the Ultra Light kit is a no-compromise option that balances performance with proven reliability.
