Works for me - Meprolight TRU-DOT Smith&Wesson Fixed Night Sights

I paid a gunsmith to put it on (not many left for S&W revolvers.

Looks great and certainly has helped me dry firing in the house.

I havent taken it to the range yet, but I have not doubts they have been installed correctly.

I took a star off (probably should take two), they are not easy to install correctly, according to what Ive seen in YT vids.
If you know what you're doing when installing, then I definitely recommend these.
