Samuel Colt's Paper on Manufacturing Revolvers

Seems to me that if the arbor hole is drilled to the right depth then the only thing that will really wear is the wedge. Maybe a nominal amount of wear to the edges of the wedge slot. I cant see driving the wedge in deeper changing cylinder gap. Now on a Uberti with the deep arbor hole it will change the gap. I don't know the setup on an original Colt but seems to me they would have the arbor hole drilled to the correct depth. I mean Sam Colt designed the thing, he oughta have known.
