If you're going to do this, (G2+KL3), get the BLACK KL3, not the HA as it matches the black G2 perfectly. Some folks don't like the looks of this combination but I think it looks really neat! Nice and light, very durable and the batteries will last a long time.
Also, get a Garrity "Ozark Trails" 2XAA light sold at most Wal Mart stores. Pull out the clickie and it'll drop right into the G2 with no modifications at all. Makes the perfect G2 clickie and no worries about any "lockout" feature! Oh yeah, the belt sheath for the Ozark Trails/Garrity 2xAA light with just a little, easy shortening, fits the G2 like a glove.
