Was admiring 44 dave’s pics of the old Colt Army, and have to admit I’ve never cared much for the streamlined Colts (outside of the Police model), but never noticed the cutout on the left hand side in the recoil shield. The way it is cut seems peculiar but does line up with the nipple. However the much larger cutout on the right hand side is certainly there for installing caps. So what is the cutout on the other side for?
