1911s are most reliable in single stack, .45acp versions.
Double stack versions take fewer generic parts and are more finicky to begin with...you are therefore buying a gun that will, on average, require more repairs than a normal 1911, and has a narrower parts range.
Norinco mags, in my experience (and I do have plenty of experience with Norinco mags) belong at the opposite end of the range from the shooter. They don't seem to send ricochets back, which is the only good thing I can say about them.
