Either turn it in or out to take the slop out (personally I'd leave a bit of slop so as not to overstress the metal)
On some bodies that "pin" is a spring loaded plunger which is very nice.

Hmm, really?
Interesting
is that grub screw only ment to be accessable when you remove the grip screw? (IE, the allen key side facing down) or adjustable from the top? (Ie, when the upper is popped open, allen key side facing up)
