I've looked for an answer and couldn't find one. I'm hoping someone here will have the answer, because this is starting to become one of those "things". On my Mil-Spec, and many of the Springfield 1911s I see, the crossed cannons are located near the muzzle. On some though, the stamp is located right behind the ejection port. Is there anything special about the 1911s with the stamps behind the ejection port? Any insight on this would be excellent. Thanks all!
