On my 1911's the vibration from shooting 45ACP's loosened the grip screws. O rings solved the problem. As far as the upgraded bushings and grip screws, I think that is personal preference, if you like the look then buy them. Make sure you buy the right set of bushings and screws to match the thickness of your grips. I have VZ and Larry D grips on my 1911's and have been very happy with them. Additionally, I use blue loctite on the bushings.
