This is a tool to help you open the bottom of glock OEM magazines for servicing, those little locking tabs are so stupid!
It was a quick and dirty mod given I only had the stl to work with, but it turned out ok.
I uses one M3 15mm.
Still a pain to use, but at least I now have the screws for it lying around.
