i have a glv2 and so far it has been awesome. but i have noticed sometimes i have to push the button really hard to get it to fire. i finally noticed that the black bit around the actual part of the button that goes down is floating up a little bit and i have to push that all the way down flush with the silver part to get it to easily fire. is there any way to make it stay down other than just pressing the shxt out of the button every time??
