This Drop in Trigger Kit fits all XDM pistols including the new XDM5.25". The kit contains a striker safety lever, to remove the long trigger pre-travel on the XDM trigger. Reduced power: trigger spring, sear spring, striker safety spring and striker spring, to lower the pull weight.
The trigger is made of tough light weight polymer that helps speed up the reset. It also has an integral over travel stop on the back of the trigger. Using this method of over travel stop removes added stress on the trigger bar that are present with any of the other over travel stop methods.
When installed correctly, the kit will give you a short crisp trigger pull (about 3.5-4.5lbs) with a fast reset and shorten the total trigger pull length.
