Well as people find out 1911s can be finicky out of the box and may need adjustments even after "break-in". I have a few hundred rounds through and the only problem I had was not dropping empty mags when released. I adjusted the tension on the mag release button and problem solved. It is a Springfield loaded and shoots just great without any modifications. After another 1,000 rounds I may get the MHS changed out (hate the internal lock), lower the trigger pull a tad and change out to heaver springs.
