Not exactly an upgrade, but I have two compact slides and one appears to have some material removed from the underside and one does not. Maybe to lighten the slide a bit.
Also just received my full-size RX model and the rear sight almost fell out of the dovetail after two mags. These were the first shots out of the gun.
