S'G' barrels and those with Saginaw barrel.

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Looking for info on barrel markings/makers for second block S'G' receivers in the 3.5 - 3.65 range. 

(1) The Saginaw barrels installed on these, would they absolutely have the smaller proof P used for IP/S'G' or could there have been a large P used? I have one in that range with a Saginaw barrel and large P on it which I thought was only Saginaw SG.

(2) What proof P marks are correct for the other barrel makers, Underwood/Inland?

(3) What date range would be correct for Inland and how are they P proofed?

I appreciate any insight.
