I have been toying with getting style 1911, and originally thought to go with the STI guardian, but found it is going to be out of my price range. I have seen several lightly used Colt Commanders locally within my price range, and I would really like a series 70 Commander, but that may not be an option. I have heard of some issues (qc?) recently regarding the newer model Colts. If what I heard was right, what has changed in older vs. newer models (not talking series 70 vs. 80, just what issues have come up)? Wanna kill these ads? We can help!
