Did not fit - Williams Gun Sight Ghost Ring Browning Buckmark Rear Sight Length Over 1in - Fiber Optic Blade

I watched videos on how take off the sights and install these. Watched the best one several times so felt I could do the swap. Old ones came off ok, swapped the elevation parts, but when it came to the putting in the final pin the hole in the Williams sight would not line up with one on the gun. Gave up after several tries and put the factory sight back on with no problems. went on in seconds. I would still like to have a ghost ring, so ill keep looking.
