I need to know now!  I have a Colt Green Label 6520 Govt' Carbine.  It has the large hole pivot pin, and is a slab side. I assumed it had the large trigger pin (you know how Colt likes to play around with these things).  I cannot examine my rifle directly for a few months, but I am trying to upgrade the trigger now.  I know the green labels are unblocked for the sear, but what about the trigger pin?  Were they made with both sizes? What's the deal?  I have had reputable sources telling me different things.  Anyone know for sure?
