I seem to remember years ago they had a chrome finish for the revolver chambers that was supposed to reduce lead build up and fouling in the cylinder. I do not know anyone who ever had it done.
Foolish question...but would a chromed chamber reduce the "grip" of the cartridge within the chamber and increase pressure? I know that this is a factor when shooting tapered cartridges in revolvers and wondered if it might apply here as well?
I have been curious if one of the fancy new surface treatments like NP3 or Melonite would help out a revolver for any reason beyond rust prevention. Like would a Tennifer treated blued steel revolver be as amazing as you would think or just a funny looking finish that is nice as it doesn't rust so bad. Yikes, what if Glock made a revolver... That would either be amazing or scary.
