For the money, you can get better quality from any of the great 12 makers out their and some great customer 1911 gunsmiths.
And accuracy is largely dependent on shooter skills so long as the firearm is reasonably well built.
I get sub-two inch groups with several of my Glocks, Sigs, and of course, my P7s. Offhand Weaver stance but that's taken me three years of biweekly visits and several shooting sessions with really great bullseye and regulary competitors to pick up skills.
