The mags dropping free also has a lot to do with your Scorpion.
Every single mag I have put in my Scorpion drops free, no modification. I push the eject forward with my trigger finger and they all pop out at mach 2.
10, 20, 30 round CZ factory mags (the old smoke ones), Mantacore 32s, PSA 35s.
They all also hold open on the last round.
First gen pistol without trigger weld.
