sachel 45: Both Kings and Wilson make drop in beavertail grip safeties for the 1911s - you may have to check and see if there is a specific one made for that Officer's Model you have. That should help with the bruises.
As for sights - one of the best looking, non-dragging set of sights I have seen is the Nowak sights - but, they are dovetailed into the slide so you would need a gunsmith to do that (it's recommended).
Check the Brownells catalog if you have one, they should have everything you need to dress that Offcier's Model. HTH. Mikey.
