I have a set of New in Package Uncle Mike's 59012 Round to Square Butt Conversion Grips. I could probably make these fit my SQ butt 686, but don't want to ruin a good set of grips that someone can use since these are hard to find and no longer made. Will trade for a set of Uncle Mike's 59005 square butt grips in decent condition.
I modified these grips to fit my square butt revolver.They did not fit the L frame very well. Perhaps they will fit a k frame better.
