I dont have a problem with rust.I keep ALL my weapons cleaned and oiled,especialy my carry weapons.
I guess every blued pistol with holster wear on barrels and cylinders should be reblued so they wont rust?
As far as stealthy...I carry nickel plated snubbies,and highly polished stainless steel snubbies,and 1911's also, that are a lot shinyer than the chambers on my Rugers.
But to each his own I guess.
I for one, like the look of the polished chambers.
