I have a Kimber Tactical Custom II and recently acquired a Sig 1911 carry. The Kimber trigger @4 lbs is about a pound lighter than the Commander sized Sig. I also notice that the hammer is a lot stiffer on the Sig. I wonder if Kimber uses a lighter mainspring than the Sig and if balancing that factor might bring the triggers in close?
Does anyone have information on this or do I just need to swap them and remeasure?

thanks, Ron
