Gentlemen, I see what Gunman is trying to describe and tend to agree with him. I cannot speak for guns such as Holland's but believe his statement to be true for the vast majority of guns. For instance, a 2 frame Parker has a set distance between the firing pins and whether the barrels were made 26", 28" or 32" they touch at the muzzle. And I seriously doubt there was any tweaking of the chokes to change point of impact. In a factory setting producing large numbers of guns there simply wouldn't have been time for such niceties. And no one is going to convince me that makers in the Gun Quarter in Birmingham took their guns to a shooting area outside of town and went through the profitless process of regulating POI on each gun. It just makes sense the tubes were carefully joined on the same plane and that was that. Just MHO so pardon my ignorance.

John McCain is my war hero.
