Any thoughts as to why a two piece hing pin would have the slot on the right side of the reciever as opposed to the left. Is this a quick half a_ s fix to putting one back on face or some other trick? Does anyone have any experience with this?
Does it indicate some serious issues typically?

| The hinge pin is not the hinge, the roll is the hinge surface, and the pin goes through the roll. You sometimes see this where the gunsmith installed the pin backward.

| Just stand it in front of a mirror in the gun rack so it won't annoy you.

| Why would turning the hinge pin be a "half a*s fix" ? It's just too bad all SxS's don't have an easy way putting them back on face . Paul

Ans: Its not. Its not a fix at all. Because the pin goes through the guide roll ( a bushing), the barrel lump hinge surface bears against the guide roll, not the pin, so reversing the pin doesn't do anything except get the screw end of a two piece pin on the right side instead of the left where it should be.
I assume by turning you mean reversing. Axially rotating the hinge pin should not have any effect on the hinge either.
Pressing out the pin and inserting a new guide roll was an easy fix when the Parker Bros tooling existed. Now, I understand that many of the pins are rusted or seized in place, and you need a hydraulic press and frame support blocks. I don't know how Turnbull puts them back on face but I understand when they re case color the frame is completely stripped out, so they must take out the pin too, and then re install some type of pin during the annealing and case hardening process to prevent warpage. I hear some people say that the only correct way to put the barrels back on face is to r&r the guide roll, others say just TIG weld added material to the barrel lump and re contour. I don't know know enough to know what is the best way.
Is your new G from Mike Jensen? He had several decent ones he was selling.

| The guide roll is what I was referring to. A friend bought a Parker slightly off face. He pushed the guide roll out, rotated it , and bingo, back on face. I would have to assume the pin slot was in a new position. I've never done it, just what I've been told; and yes, I saw the gun before and after. Paul
