I recently purchase a series I stoning fixture from Brownells for the expressed purpose of doing a trigger job on a new Springfield Range Master 1911 in 45acp. The trigger pull was around 8lbs. A simple stoning and replacement of the sear spring and hammer spring has resulted in a trigger pull of 3.5 lbs as recorded on my electronic trigger pull machine thing. The wifes Kimber registered at 5lbs and I did the same to it and the results were average trigger pull of 3.2 lbs.
Would anyone care to share their results?
