Norinco 1911A1 great buy
I have to agree with White7 - The Chinese Norinco 1911A1 is a very nice firearm, made from recycled railroad rail steel. It is some of the toughest steel I've ever run across. Out of the box, It was a very pleasant experience, with good accuracy and feel.
I added a lot of Wilson Combat and other other parts, and doing the machining operations was mind blowing - I have never run across anything harder to machine. There's something to be said for work hardening by millions of tons of locomotives and boxcars over many years! I've read where people have run 1,000's of rounds over the last few decades through a stock Chinese Norinco, with no failures or noticeable wear. That is the reason the relatively few samples in this country have been used as the base for racers by many talented smiths - It's a phenomenal starting platform by anyone's measure.
The later Turkish Norincos are another story, avoid those for sure. If you are lucky enough to find the original Chinese version, be sure and snap it up - You won't be disappointed!
