Sorry, correction: reset reduced approx. 2/3. Trigger pull reduced approx. 20 ozs. in DA and 6 ozs. in SA.
Polishing trigger bar, hammer strut top, hammer base and internal, sear, and disconnector will help smooth the action. No need to polish the GG control latch. Installing nickel plated flat sear spring will smooth action too. Of course installing a lighter hammer spring decreases pull weight also.
