If you remove the right grip........carefully of course; you will be able to observe the mag button/hold-open interface. At the mag button's highest point is when the hold open is engaged upwards, when the button is lower, it does not engage the hold open. I have never experienced a too strong hold open spring myself, but as usual, not out much either.
One might surmise that the button is too small a diameter, the mag's recess for the locking piece is worn, or perhaps the push button mag locking surfaces have worn down.
guess could be a physical interference between the grip/mag button........only near the top of the magazine body area........
Just guesses in the blue..........something to look at anyway.
