Springfield 1911 mil spec

[XD40FAN]

Picked this up at the gun show last weekend for 400 bucks. cerakoted ordered grips. Now as far as the trigger hammer and springs wanted to know what your thoughts are? I want 3.5 to have 4 lb pull and it to be smooth as butter! Prefer black not stainless due to the color scheme skeletonized or standard doesn't matter even though the skeletonized does look good! What do you think?
