One thing which I have always wondered about, so this seems like a good place to ask. This would of course depend upon the actual model of gun in question, but many doubles over the years have been built with the same bar for different gauges, only the height & width of the standing breech & spacing of the firing pins being changed to accomodate the different sizes. If this be the case would not a gun built on a 16ga be stronger than one built on a 12ga as the leverage applied to the breech would be lower? If this is a model in which the entire frame is slimmed down for the smaller gauge this would of course not be true.
