You're welcome to MY old one - and ALL others.
Now all I have to do is raise the money...
I've owned an even dozen Norincos, now down to six, and I've been involved with about three times that many more to some degree. Either a little tweak on an extractor or polish up a disconnect or eliminate a little grittiness in a trigger...to barrel replacement and fitting to slide/frame tightening. Back in the day, they sold a lotta Norincos in this area. They were literally everywhere you looked, and they were generally well-liked...because in spite of the "Diamond in the Rough" niche that they occupied...they flat ran.
The general concensus was along the lines of: "Well...it ain't pretty and it's not bughole accurate...but I can't get this thing to choke."
I knew many more people who owned'em in multiples, having been duly impressed with the general performance, they went back and bought one or two more. Around here, we're very big on the "Two is one and one is none" philosophy.
The early ones often had barrel fit issues related to insufficient vertical lug engagement, and it was a slide/frame dimension problem. That problem seems to have been corrected after about a year, as the percentage of bad ones was low. I've personally seen only three with that particular glitch, and it was a bad one. They'd beat the upper barrel lugs to gobbits within 500 rounds.
Of all the Norinco "Model of the 1911A1" pistols that I've encountered...there was only one real lemon. A good friend in Tennessee picked it up at a gun show, and realized why the price was so low after his first outing with it. It had every problem known to the 1911 and a couple that I'd never seen. Like running the fault codes on a Ford, I had to start at one end and work my way to the other. I wound up with about 25 hours in the thing before it finally submitted to my whims and started to behave like a proper 1911.
I now refer to it as "The Nork from Hell" whenever we speak of it. He calls it "The Rehab Nork." He reports that it's been 100% ever since I ran the gauntlet with it, and I have to admit that this one nearly whipped me. I'm not one to give up easily, but I was ready to buy it from him just so I could take a big hammer to it to keep the demons that inhabited it from escaping and possessing other innocent pistols.
Maybe you were unfortunate enough to have had its evil twin.
