Is it possible for the chamber walls to be too highly polished?

[CTSigLover]

I know that in a revolver, the chamber walls should be uniform, and without major machining marks, and that rough chambers can be "smoothed"; but is it harmful in any way if the chambers are too "smooth"?

I am looking at a Model 27 which has chambers as smooth as glass, I have never seen chambers this smooth on any factory Smith, and it seems obvious that a previous owner had them polished to a mirror shine.

Provided the chambers are in spec, do ultra polished walls hurt anything? Does the case need something to "grab" onto during firing? Never ran into this before, and would appreciate your thoughts...

No, don't worry about the chambers being "too smooth".

A couple generations ago, before production managers got so cost concious, S&W used to burnish the chambers, producing an extremely uniform, high polish surface for reliable extraction. That is no longer the practice, of course. Just enjoy your easy extraction and don't worry about it!

Yeh, what john said.
