I just picked up a Ruger Redhawk and some previous owner replaced the Ruger sights with a couple of fiber optic (Tru-Glo or some other such make) sights. Two green dots in the rear and one red dot in front. Problem is the gun shoots high (apparently the other owner just scoped the thing and left the sights where they were) and the rear sight is all the way down. There's no more room left to drop it any further. Front sight is fixed and no amount of coaching will get it to grow. Has anyone had this experience before? Can I file a smidgen more off the bottom of the rear sight to try and drop it more? It shoots about 4 - 5 inches high at 25 yards. Maybe the front sight needs to be different? Try a shorter type and the rear readjusted again? Does anyone make a different front sight that would fit the Redhawk? Any ideas other than going back to the original Ruger sights (which I don't have). Thanks guys....
