I started with a base Compact 1991A1.
Before as stock:
W.I.P., I fitted a "drop in" Wilson Beavertail grip safety, and a Fusion Magwell. I also relieved the slide and installed a Kings recoil reverse plunger recoil system, and installed and fitted a Storm Lake Machine replacement barrel and bushing:
I kept the stock Colt hammer and sear, but polish and improve the trigger pull according to the instructions in Kuhnhausens shop manual (1911). I then sent the pistol to Bob Cogan for hard chrome finish, installation of low melt STI (Bomar clone) adjustable rear sight, and, a dovetail fiber optic front sight. Other goodies include an STI trigger, a Brown extended mag release. These features are personal preferences for my carry Colt Compact.
Finishing it off with custom thin profile grips and bushings by Ezmeralda:
Some folks will argue that one doesn't need to make a belly gun into a target pistol. I wanted a compact 1911 pistol that will shoot at close range, and extended range. This is my personal weapon, and it is set up as I want it. Just some ideas as to how far you can go.
