Try reversing the latch,When I first shot mine a number of years ago I would barely tap the release with out knowing it and the mag would drop while shooting.plus, my thumb was not long enough to reach the release and I had to change purchase on it when pressing the release and change again to shoot it.reversed the release and no more problems plus,I could release the mag with my right middle finger without changing holds.maybe try it and let us know what happens.good luck.
