I just got my order in with some of the AW IMR 16340 batteries. I like the performance better than the non-IMRs, but I noticed that the battery does not fit as snugly. There's quite a bit of wiggle room inside the tube, and I can feel it jiggle both side-to-side and up-and-down. The side-to-side wiggle should be easy to fix by just wrapping something around the battery to wedge it in a bit, but I'm not sure of what to do to fix the up-and-down jiggle. In order to get it to fire I have to press the button pretty much all the way down, and it feels as though I'm pressing it down more than I should need to. Any ideas?
