The rear sight on my new 686 has some forward/back and side-to-side wobble in it. Is this normal for a new gun? I'm thinking about replacing it with either a Weigand Competition rear sight blade or a Millet rear sight. I don't know what size to get or which is better. Anyone know anything about these sights? How wide is the gap in the factory S&W sight? Ill leave the front sight alone if nothing needs to be done to it.
