On the color issue, just to illustrate what dfariswheel is saying.Ways to ID a nickel versus stainless Python:
Nickel has a slight yellowish tint, stainless has a "white" color. Compare the gun to something known to be made of stainless steel, like a kitchen knife, and if it's nickel the color difference is usually obvious.
Sorry, what model? There is no "Colt Hammerless" revolver model.In reading this thread I have a question, on a Colt Hammerless how do you
tell the difference if bright stainless or nickel plated finish other than color.
Are these stamped with a S or N aswell???
Once you can recognize this distinction, its night and day, even at night.The nickel always has a bit of yellow tint. Stainless is white.
It's not the carbon, it's the iron itself. Chromium & nickel added to the steel do not affect magnetic properties very strongly. Almost all stainless steel alloys are magnetic.Magnet; but sometimes SS has enough carbon to attract magnet too.
