1911 trigger job

[alexs]

I bought a new SA 1911 long slide. The trigger was exceptionally bad, not smooth at all and I'll guess 7++ lb. pull on the trigger. I followed on line suggestions on improving it and now have a much smoother, much crisper and much lighter trigger that now measures a light 4.5 lbs. If it stops here I won't complain. But If possible I'd like to get it better. I brought the hammer notch to .0020, snipped 2 1/2 coils off the hammer spring, polished most everything with #600 then polish and a dremel. Any advise where to go from here? What I particularly had difficulty with is polishing the groove where the trigger bow slides, especially in the corners.
Don't laugh, but the best thing I found for this groove was folding a crisp line in #600 wet/dry paper and wrapping a small piece of square cornered wood. I used a cut down paint stirring stick. This is very tedious and doesn't get in the corners well. Please give me a better idea.

The other item you haven't mentioned is the leaf spring.
You may want to adjust this for less pre-load.
Don't go too light or the trigger will not rebound quickly and fully.

Nothing gets in the corners well.
I use fine jewelers files to make sure there are no burrs or other roughness in the trigger groove corners and call it done.
Make sure the trigger bow edges are not square and sharp to reduce drag in the bow grooves.
