I like my NP-29 a lot, enough that I'm going to buy another and re-barrel it to 9X23...
They are very tough pistols, although the finish is not as pretty as that on my commercial Colts, it is as good as on the original Colt USGI 1943 pistol that I also own. it is after all built to USGI specs, and the parts will interchange with other 1911's (except the grip screw bushings).
This relates to the 1911 variants from Norinco only, as I have no experience with other Norinco pistols.
2 cents Eh!
