Put this in my wife's S&W J frame 327 Federal gun very nice.
So my wife's J frame S&W 327 Federal 3" the factory double action only gun was at 11lb 12oz pull. It was brutal to pull and quite bad. Put this kit in and it dropped to 8lbs and 6oz pull and it much much nicer. Not a light primer strike to be found.
I have only tried 3 of the clips with this gun with some trial loads. These were the Starline specific clips. They worked fine they loaded fine with the TK Custom moon clip loader.
