they do not work on the sbh. you might get it to fit, but good luck sighting it in. ruger will tell you that right out of the gate. to keep advising folks otherwise is wrong and irresponsible.

None of front sights listed for Super Redhawk are listed in SBH Hunter booklet. However, plunger and spring are the same and I wouldnt be surprised if Super Redhawk front sights go on Redhawk and SBH Hunter. Better yet, if somebody has all listed revolvers I would appreciate the test to see if Super Redhawk front sights fit Redhawk and SBH Hunter because I already have Redhawk and thinking of getting Hunter Bisley.
As you correctly pointed, rear sight adjustment could be the problem with front sight from Super Redhawk if they are installed on Redhawk and SBH Hunter. Measurement of their heights should provide the answer.
Any correction, if something isnt correct, is appreciated.
My apology for late reply, Onty.
