I was able to find someone in Westhampton, and got my sight switched out. An older retired machinist guy who seems to do gunsmithing out of this gun shop located in the Westhampton airport:
friendly and talkative guy, works from a small bench in the store, and he was very interested in showing me everything he did so I could do it myself next time. I would say the front sight is a bit off center, but he thought it looked centered. I’m heading out to try it today, we’ll see if I have to tap it over a little.
other places I called talked about dropping off, and waiting two weeks for it to come back, and some people I talked to said they have had things come back wrong and then you need another two week turn around, so I was very glad to find someone who could do the work while I waited and watched.
