My selector didnt work at first either, needed some work. The peice inside the grip can slip off because the AGM version doesnt have anything holding the top of the left grip tight, so the plastic selector peice inside the grip can spring off the metal peice on the selector by flexing the whole left side of the grip(the whole removable cover). I just used a couple of shims to push the metal part of the selector closer to the body so it can't be sprung away enough to not work, now my selector works perfect. I just had to lube the crap out of the shims to make sure there wasnt extra wear.
