As indicated above, Springfield 1911 do not have the Series 80 firing pin block. An easy way to tell if a pistol has a firing pin block is to first MAKE SURE THE PISTOL IS COMPLETELY UNLOADED, then cock the hammer and push the firing pin forward with the tip of a pencil. If the firing pin moves forward, the pistol does not have the firing pin block.
Allen, did you by any chance purchase a stainless Springfield at Patriot Arms in Brandon, Florida last Friday?
