Possibly Dumb Hard Chrome Questions

788 Views 3 Replies 3 Participants Last post by  OCG1911
1) Which parts should get plated? - Just the frame and slide, or the internals (barrel, hammer, sear, etc.) as well.

2) Does plating significantly change the dimensions of small parts and holes, pins, dovtails, etc.?

Len,
Have everything plated except the sights, springs & grips
I personally don't do my barrel as I don't want any plating inside the bore. Not an inditement, just my personal preference.
Hard chrome builds up an avaerage of .0002" per surface. It tends to build a little bit more on edges and corners, than on flats.

Ok, please bear with me on this. In looking at Kuhnhausen's dimensioned drawings and the tolerances on them, it seems like an average .0002" build up wouldn't be enough to throw the fit of pins, etc. out of whack. E.G. A minimum hammer pin hole in the frame and a max. diameter hammer pin would still go together after plating. Correct?

Also what about surfaces like a fitted sear/hammer or sear/thumb safety. Any concerns there?
