Springfield. Every one I've seen and handled, including mine, has been 100% out of the box.
RikWriter, I know this is gonna toast you, but every Kimber I've ever gotten my grubby mitts on has been less than exemplary, reliability-wise. Example: at my last PP class, there were three 1911s, a Kimber, a Baer (!), and my Springfield. The Baer and mine shot the tightest groups and never malfed. The Kimber hung up on every other shot. That and the fact that Kimbers have the highest rate of return of all 1911s at my shop have convinced me that they're not All That.
