Why not?
Clipdraw does not make one for a K-frame, but I had a spare J-frame model, so I tried it. It seems to fit decently.
My only concern is the supplied screw that replaces the OEM plate screw. Do the K-frame and the J-frame use the same screw pitch there?
the blued screw I used seemed to thread in smoothly, but if it's a different pitch I need to rethink this.
