I'm always finding intriguing that during the discussions here a lot of members are usually expressing years of experience and thousands of rounds with the particular firearms. However on the exchange forum it's very hard to buy a used firearm with more than 1k rounds on the clock. I wouldn't call everything Norinco "junk". I own excellent quality SKS by Norinco. I used to own a semi-decent 1911 that would make a good platform to build on, but I've also owned another 1911 from China that wasn't properly heat treated and M93 copy that disintegrated in my hands into many, small parts on the 3 magazine since new.
Perhaps it's worth noting that this 1911 by Tisas was tested South of the border for the last 6 or 7 years. There is a video made by Hickok 45 dated back to 2013 reviewing Tisas 1911A1.
Personally I would buy another Norinco 1911 if the price would be around $300. Anything over and it makes more sense to buy better pistol for slightly more. Cheers.
