Both are great 1911's. The Norinco is an exact copy of the Colt USGI pistol only with tighter tolerances. Great for a custom pistol base. The Springfield has a few more modern refinements like a throated barrel better sights and lowered and flaired ejection port (except the USGI version).
The Springfield "loaded" is a good value with all it's custom features. Most likely things you will do to a 1911 later.
So decide what you want to do with your new 1911. Target shooting, competition ,plinking or carry with hollowpoint ammo, go with the Springfield loaded model. If you are planning on having a custom pistol built, carrying with ball ammo or casual plinking...go with the Norinco. Both are excellent 1911's.
I'll make this really simple, BUY BOTH.
You won't be sorry.
