Kit includes one of each- Ultra Low Mass Sear, Litespeed II Hammer, Race Disconnector Drop in for exceptional trigger on 1911 style pistols.
Manufacturer offers lifetime warranty. Just ad an EGW Sear Spring and an ISMI 17 lb mainspring for the ultimate trigger. Springs below 17 will cause light primer hits and slower hammer drop time. Tuning is necessary as with any trigger kit regardless of claims.
Ultimate Trigger Kit is great!
As usual, the Extreme hammer, sear and disconnector is a treat to use. The parts are prepped for an awesome trigger pull, all you need to do is adjust the sear spring for your liking, then it's off to the races!
