Easy question, looking for "reversible" methods I can use to darken the partridge sight blade on my nickel 19-4? I love the look of the gun, but the nickel sight in daylight turns to nothing!
Most of us use a Sharpie. It comes right off with rubbing alcohol. Vintage target shooters used to use candle smoke to blacken and dull their sights. No harm (unless you get wood or plastic parts too close).
BTW, it's Patridge, as in the inventor's name, not Partridge as in a pear tree. :-)
