Is the hammer in 29-10 the same as 29-2, for replacement purposes? In other words can you put pre lock N hammer in gun with lock and MIM parts. I’ve never had a Hillary Lock gun apart.
Just a side note: one of the main objectives of MIM parts was drop-in capability when the guns are produced, and for parts replacement as well. Although not always appreciated by traditionalists, MIM parts achieved that as well as economy of revolver production to keep prices competitive.
In your case the advantages of MIM PARTS will be to your benefit when replacing your hammer.
If two parts are the same dimensions shouldn’t they be equally easy to replace, regardless off method, milled or MIM?
