If the sights are Trijicons they will relamp them for $53.00 a set, just go on the web page and look under services. I just had my 6906 revamped you send in the slide and they do everything else.
I have looked for some but could not find anything. The 469 does not have any rail to hang one onto and Crimson Trace does not make a laser grip. If anybody finds something I would like to also know.
Call me crazy but I just bought a new generation 3 and it did not have a magazine safety from the factory just a cautionary sticker on the slide. I guess God and S&W have a difference of opinion so do what you want.
