Cylinder & Slide Ultra Light Speed Ii Kit

The Cylinder & Slide Ultra Light Speed II Kit is a complete trigger upgrade for 1911 pistols built on Series 70-style frames, engineered for shooters who prioritize fast lock time and a crisp, light trigger break. This kit replaces the stock trigger group with precision-machined components designed to deliver a 3 lb. pull weight—low enough for competitive shooting and fast enough for tactical work, yet controlled enough for reliable ignition. Each part is wire EDM cut from bar stock, honed, polished, and heat-treated to withstand thousands of rounds without degradation.

Speed is the name of the game here. The low-profile, skeletonized hammer is relieved to prevent frame rub and engineered for minimal mass, which cuts lock time down significantly compared to standard 1911 triggers. Deep, aggressive serrations on the hammer provide secure thumb contact for fast, positive cocking—useful whether you're running the gun at a match or working through drills at the range. The ultra-light weight sear and disconnector are matched with properly calibrated spring weights to ensure you get exactly that 3 lb. pull weight out of the box, with positive ignition every time.

All profiles and through-holes are machined to mechanical spec, so these parts fit Series 70 1911s with little to no hand fitting. The kit contains everything you need to swap out your trigger group: hammer, sear, disconnector, sear spring, and hammer spring. This is purpose-built for shooters who want a competitive edge without the hassle of custom gunsmithing.
