I've done a good load of searching up and down the forums to no avail, as most problems were either fixed by soaking in silicone or left without posting how the problem was fixed.
In my case, 2 mags KWAGlock19, both leak from the square area surrounding the fill valve
So I'm thinking part #220 isn't fitting properly with part #202, and have a keen feeling the square rubber ring holding them together needs some work...
So here I am trying to remove the pins that hold the bottom of the mag inplace and I can't bloody do it!
First of all, am I tackling it the right way? Is there a workaround? Would externally sealing it carry any consequences? What if I just spread some epoxy over the crevise? (Ofcourse i'd leave the fill valve unobstructed.. that isn't leaking yet)
PS: Found the leak by submerging it in water. Please don't tell me to do it again

Thanks in advance for the replies!
