But wouldn't it also be true for an all stainless gun to prevent galling?
I know galling was a real concern with early stainless guns when the rubbing surfaces were of the same heat treatment.
I thought it had mostly become a non issue of late. I really like the feel of the all stainless guns and I run grease on mine.
I can see some bright spots where surfaces have had contact but I do not see any evidence of galling.
