As posted by some above only on the pre war 357 Mag. Reg mag at first and carried on to the non-registered mag thru WWII and on the same PW Transitional model.

Occasionally these are found retrofitted to other pre war N frame target models. Have also been found on factory reworked fixed sight N frame models converted to target models at the factory and by private gunsmiths.

The ribbed pre war sight should not be construed by the above as being standard on any target models other than magnums.
