The fore end iron is the weak point on 3200's. The pin that goes through the iron to hold the ejector hammers weakens the stamped fore end at a critical place, and they will often crack there, and that results in a space between the wood and iron. Also, there were two different designs of how the wood was attached to the iron. The earlier method used two vertical screws attached to the metal plate surrounding the fore end latch with two slotted nuts inside the fore end. The nuts just pinched the wood between the two pieces. Later fore ends hat the screw and rear slotted nut, but at the front had a slotted head screw that went through at an angle. The wood could be pulled back against the iron by loosening the rear nut and tightening the front screw, then re-tightening the rear nut.
