Having been there, I'd strongly recommend shooting at least 500 rounds through it before changing a thing, except maybe grips or sights, if you really hate the OEM ones. If your 1911 happens to be reliable out the box, then many add ons are subjective to the user. But to answer your question, Wilson does make nice parts but some may need fitting in your particular pistol, while others may not. My tactical had a bad sear spring from the get go so that was a change I made ASAP. Good luck!
