"In fact, it seems the opposite is true... the production grade Colts seem to consistently be much more reliable right out of the box than the premium and super-premium priced 1911's."
Seen the same thing as you with the series 80 and 91 Colts. Southwestern distributor- LM Burney stopped ordering Kimbers a few years ago because he was having to return between 1/3rd and 1/2 of them. Doesn't know if they straightened out their quality control or not as the guns are so expensive he declined to re-order.
Springfield Armory went through the same thing right after they switched over to titanium firing pins and some other gimcracks. Current ones seem to work.
