In the future I plan on an aftermarket trigger. In the meantime I'm having to work with what I've got. I've cleaned the trigger with brake cleaner, very lightly lubed a few spots, installed a lighter spring/wire and adjusted it as far as I feel safe. If I were to polish the sear engagement (Not enough to change the angle)and any other points that could be causing resistance would it be worth it? Is there another spring that I can buy to reduce the pull weight some more. I'd like to get it down to a smooth 3 - 3 1/2 lbs. thanks, Paul
