In the seven years I have been using or carrying the BT-380 both open and finally concealed, I've only seen this requested once before on another Bersa site. IIRC the only solution was that someone solved this particular problem by grinding down the pinky extension flush with the base of the extension. I'm thinking that Bersa warranty would not be impressed.. There is a guy who's user name is bersasales might have a better answer. Best of luck on your inquiry.
