I picked these up loose and believe they are Herretts, but not sure.
They did not come with a screw. If they were Herretts would anyone know what the thread size is?
They fit my j frame except for a conflict at the thumb latch, so I doubt they were made to fit a S&W.
Thanks.
Those are older Herretts Shooting Stars. Newer Shooting Stars have vertical striations on the front strap rather than checkering wrapping all the way around like yours.
They originally had a blued screw which you could obtain from Herretts. I don’t have a thread pitch gauge but they use a standard SAE threaded machine screw. Just take them in to a hardware store and try different screws out of their bins. Since my local hardware didn’t have stainless I’m happy with a brass screw in one of my sets of Shooting Stars. BTW, that’s nice looking walnut.
