If the ejector hammer in the forend wil not stay cocked even after trying to cock it with a wooden dowel it is likely that the ejector hammer is broken. There is a ninety degree cocking catch (for want of a better word) that is cut differently than the original Parker ejector hammers were. The process was probably an oversight in machining the Repro hammers and, had the Japanese engineers given it a bit more thought they would have cut the inside of the ninety degree catch on a radius as were the originals to eliminate a stress crack and subsequent break at the sharp cut of the inside 90. One of mine broke and I finally had to buy an original hammer and have it fit and timed to my gun. I hope yours might be a simpler fix.
