Well I bought the kit a month or so ago and was waiting for the "perfect" day with nothing to do so I could take my time. Installation went EXCELLENT with very minor fitting. Was going to polish the parts but everything dropped in so nicely I didn't see the need to. The part that took the longest for me was fitting the overtravel stop on the trigger. I checked for fire and reset a countless number of times and works great. My only minor issue is when I pull the trigger it seems to push the slide "up" ever so slightly and when I check for functionality when pushing the slide down nothing happens. Does this mean I need to remove more material from the integral overtravel stop on the trigger? I just want to make sure I understand it correctly prior to taking off more material.
