Yes, I have also considered a gold bead sight as an alternative. There is one from SDM that would fit the bill. I am also planning on getting the Brownells Competition Rear Sight Blade to pair with it. This item would provide a deeper, slightly wider rrear notch and I think these two items would provide me the improved sight picture I'm looking for. Neither of these products are very expensive either.Good question and sadly one that I can’t answer. I don’t think that I can recall ever reading on any of the various sites that I’m on anyone ever installing a fiber optic site on a ported revolver .
However, I have read many times on the Smith & Wesson sites that a Lot of folks have installed the gold bead front sight to great satisfaction.
