Smith 686 ?

Drill/tap a 25-5 for a red dot mounting plate. Only needed one screw hole.

I've always been a SW revolver guy ( and collected them heavy at one point in my life). Love my L frames. That said, these days I'm liking their Ruger GP100 cousins just a little bit more than my 586/686's. The balance and recoil control just seem better on the Ruger. It's interchangeable front sight is a game changer for me as well. Your mileage may vary.
