    I assume that you are talking about locking back the slide while you still have ammo in the magazine. they should work just like the 17 round mags I suggest that you take a follower out of the 17 round mag and try it in the 20 round mag. I would also try shooting the 20 rounders with 10 rounds in them and see if it still has the problems ( to strong spring). You can also load 20 rounds in them and let them sit for a while to loosen the springs other that that I suggest call in Beretta to ask for any insight on the problem Beretta contact 1 8002373882
