Are 686 no dash 6" barrel have screw in barrels? Did S&W apply some sort of cement on threads prior to assembly? There is a reason I am asking
It may be an optical illusion but it looks like the lug under the barrel is not in vertical alignment with the barrel when viewed from the front with revolver in an upright position. My 686 shoots consistent LEFT (like 4" @ 30') no matter ammo and my adjustable rear sight is adjusted as far as it can go to compensate for that. My cylinder to barrel space is in spec.
What I gathered from that post was that with the frame vertically oriented, a vertical line from the center of the underlug would not pass through the center of the bore, because the underlug is shifted to one sideI dont understand how the barrel can be misaligned with the underlug, they are 1 piece. The whole barrel and underlug assembly could be canted
