The Springfield milspecs are definitely hit or miss with regards to quality. One friend I shoot with bought one and it was 100% reliable and fairly accurate out of the box. Off bags at 50 feet it would do 2 - 3 inch 7 shot groups.
His son's was somewhat in between his and mine regarding accuracy and reliability.
Mine on the other hand was a major POS. It was back to the factory 2 times with no resolution of the accuracy, fte, and mashed brass problems. I ended up taking matters into my own hands and several hundred dollars later it is a fantastic pistol. After a set of BoMars, a Kart Barrel,heavier Wolff recoil spring, Wilson slide stop lever, Wilson mags, and Ed Brown extractor it better be.
If you aren't expecting a lot from a 1911, want to educate yourself on how much hell on earth a pistol can be, or plan on customizing anyway get a Springfield. Otherwise, get another Colt.
