Hang on there a minute. Norinco's have forged large parts, machined small parts, no MIM, and are pretty good right out of the box. The steel is harder than most other 1911's. The last I heard, they were one of the few 1911's that Wilson Combat would work on. It is not a poorly made gun, by any measure.

Not sure where you got your Norinco or when but I bought one about 20 yrs ago new. It has maybe 500 rounds sent out the barrel. I can hold it in my hands, shake it sideways and listen to the slide as well as other parts rattle. Granted it does work but has very ill fitting parts and I will not be buying another.
