the fact that many production guns are not adequately regulated is a reality based on quality control.
the cure for that disorder involves mastery of sophisticated tools, and that is artistry.

Or another possible cure is a redneck with a file. đ
I have found it pretty easy to move poi with a file, but the problem with that method is that you can only center one load. If it's a single purpose gun, like a turkey gun, that's not that big of a deal to me. But for most of my guns I want them to shoot straight out of the box or I don't want it.
My theory is that it's impossible for any sxs gun to center all loads. It's gotta be regulated for a load appropriate for the gauge, but I have owned several that wouldn't center anything. That's a result of lousy construction.
