You need a software upgrade. Take it from someone who had the same problem you do. It took a very long time for me to "untrain" that habit, having walked around for years in my youth "monkey fingering" the triggers on my bb/pellet guns. It is also the reason I shied away from glocks and told people "I'm just a Beretta guy". Even after retraining the muscle memory of my trigger finger, I still own Berettas, but this will eventually change as I am getting closer and closer to making the transition to those ugly soulless glocks.
You can own both, ya know?!
Toughest transition for me is going back to Beretta from Glock, as the slide safety invariably gets activated when racking the slide.
I still love the Beretta as a piece of mechanical art, though.
