After owning a couple of STI's, I figured out I replaced most of the innards anyway. So instead of buying an Eagle, bought a 2011 frame, a Caspian slide, Kart barrel, Cylinder and Slide trigger set, Dawson sights and then had it put together by a good smith and cerakoted. Some fine day, someone will finally be able to explain why a .40 shoots so much "softer" than a 9 or 45 at the same power factor. But for now, they just do. And going to the 2011 cures 99% of the magazine problems that ran me away from single stack 1911's.
