I really have no doubt that Armco tuned Norinco 1911's will be delightful to shoot but with shipping and taxes, you'd be exceeding 500 bucks.
Now a lot can be said good and bad, about a stock Norkie, rough slide with a gritty creepy trigger and all. A buddy acquired a very slightly used, stock Norkie Commander, and took up reloading on a shoestring budget. He was practically a handgun virgin when he bought that Norkie and now after approximately 2,000 rounds through it, he can consistently group 8 shots into 2.5 inches off hand at 15 meters. He has probably dry-fired a few thousand as well, and continues to do so. He's had a few stovepipes or failures to chamber while experimenting with his handloads (COAL, powder charge weights, crimp, etc), but after he developed his loads, he has had zero FTFs or FTEs.
His Norkie Commander is and has been functionally reliable from day one.
The trigger, slide and almost everything else that needs to, has smoothed out by now. Admittedly the trigger is still a little creepy. But my friend is now a good pistolero without needing a tuned Norinco. He put his money into a simple reloading rig and components.
So if you want a 1911 to play with, or learn to shoot a centerfire combat handgun in 45 acp, I unequivocally recommend a Norinco 1911. Box stock. Try to find one with a factory beavertail safety because that is the only part I would add, to prevent hammerbite.
Before taking up shooting my buddy researched and talked to me, explained his goal...to be a good .45 acp shooter with the least possible expense. He also soaked up the advice of several experienced shooters/buddies.
I am proud to say that he had the sense to listen to sound advice
He bought the most basic 1911 around and concentrated on learning the proper skills. A novice with proper training, learning attitude and discipline can learn to shoot well with any decent gun. I believe a stock Norkie 1911 is a decent gun.
