I have a 26-1 .45 Colt that has had a long sad story of neglect. It was stolen and mutilated and recovered before I bought it.
I sent it off to be repaired and refinished since it's an excellent shooter.
When I got it back from repair and shot it the rounds impacted extreme left. All the rear sight adjustment is required to center the group. This was not the case before I sent it in.
Upon close examination the barrel is not centered. It is turned slightly to the right as you look over the sights.
How hard is it to turn the barrel?
Right or left hand thread?
Shipping the gun back to be corrected is a pain the #&2 as I have to drive an hour to ship it.
