I am looking for a thumb latch (cylinder release) for an N frame (M29-3) and have found one online for a good price that is from a Model 65 - will it work? thanks in advance for the assistance.
maybe factory nickel-plated? Well, the thumbpiece and the gun will both be shiny, sure, but I've found nickel to be a bit...warmer?...in its luster (a little more yellow) than stainless.
But at any rate, yes, the thumbpiece should fit your gun.
ETA: please post pictures, if you would; I want to see the end result!
