I've been trying to get my dads 121 fixed. The original problem was that the ejector wouldn't eject the shells properly. I replaced the ejector, but now it won't feed the shells up into the chamber. I took everything apart and cleaned it really well hoping that would fix the problem but it didn't. It seems like the shells are pinched to hard in between the ejector and the firing pin and it won't release them to feed through. Does anyone know what the problem is?
