I know there are already threads on this, but has anyone found a solution? I have a gen 3 and my mags have a 2 next to the Glock logo on the back and a 9 on the follower so I think they are the new ones, but I am having a lot of failure to feed malfunctions. Usually in these threads I see all these posts about how their gun works. I want to hear from the people that had problems and what if any was the solution. I had the screw tight i guess, but only hand tight. When I got home after the range today and researched the issue I loosened it a turn so its loose, but won't come off. Ill take it to the range again Friday and put some more ammo through it and see how it does. I really want to be able to run this light on my gun, but I can't sacrifice reliability for it.
