I have some stuff added on mine, wilson guide rod,recoil spring,egw bushing,front dawson precision fiber optic sight. Out of those things the bushing and front sight have made a big impact specially the sight, going from just looking at a plain black front sight to actually having something i see is way better and improved my shooting. I will probably go back to the original spring but keep the wilson guide rod in.IMO the trigger is awesome and if you want to get a trigger job done to it then maybe you should shooting something else. Get some reliable mags you should be fine, some guy on the 1911 forum has like 20,000 plus rounds through his RIA and has not had a single problem and its all stock besides his sights just a fyi.
