S&W adjustable revolver rear sights - designed to cause insanity or coincidence?

I use an unsharpened pencil to compress the plunger then you can slide it right in. Saw this tip many years ago and it works! Put the plunger and spring into the screw, slide it to the edge of the sight body, compress it with the pencil and slide it the rest of the way.

I'll try it.

I just took my M17 to Frank Glenn to replace the rear blade. I appreciate your courage and perseverance. I on the other hand, am a coward.

I have done 2 or 3, and only lost the detente and spring once, the first time. Best done with sight removed from the gun entirely. I just unscrewed the screw until the detente showed, then put my finger over it and turned the sight body the final few turns. Installing, i started the screw without the spring and detente then inserted them and held my finger over them and turned the sight body until were captured.

And, be sure to do it inside a large clear plastic food bag in case the spring and detente slip away.
