Question:  How do you adjust the sights of a fixed-sight revolver.

 

Answer:  To correct windage you must turn the barrel.  But many barrels are over-torqued enough that they would be loose after windage is corrected., so you  must remove the barrel apply LocTite and realign to a collimator.  Once the LocTite sets up you cannot “whack it” with a babbit bar anymore to make further changes, so they wouldn’t go to this trouble for off shooters unless really bad enough to require changing the barrel.  Problem is that both Ruger and Smith & Wesson test fixed sight revolvers at 20 yards.  Targeting is by holding at 6:00 on a 3-inch bull circumscribed by a 6-inch circle tangent to the aiming point at 6:00.  As long as all six rounds hit within the outer 6-inch circle it is within specs.
