I just bought a S&W 6906 LEO trade in and it is what you might expect, worn often, shot seldom. The primary point of the holster wear is the black sights. They are worn clean at the corners. The choices to renew them at this point are either 1) black sharpie, 2)flat black spray paint, or 3) a cold blue dip.
Does anyone have any suggestions or experience to offer?
