Need help on 657

[keithherrington]

Just bought a 657 with a 6" barrel. Coming with a scope mount and no rear sight. What sight blade height did it come with on the rear sight?

My 6" originally had a .160, but I could not get it sighted to POI at 25 or 50 yds.

Had to swap it out with a .126.

657 sights

My 657-5 Hunter Classic with 7-1/2" bbl. had black sights: a .148" blade on the rear & .243" on the front. I changed them to a white out-lined .160" (actually .158") rear & a .252" red insert front sight. No problems zeroing it.

My S&W sight chart shows that the .146 blade was standard for both 4 & 6 inch barrels.
