All of the subcompact models will do that if they fit your hand just wrong. I got that from my old Glock 30, and my wife gets that from her Glock 27 (same size as your 26. Cane asked if you have the grip extensions and I'm guessing you do — that's the only way I ever got that. The non-extended versions aren't long enough for my pinky, so I have to tuck it underneath, and that means it doesn't get pinched. There are several brands of magazine grip extensions. I get less bite from the Pearce extensions because the groove is more pronounced a little farther below the seam between the extension and the grip. That naturally helps my pinky steer clear.

"After a shooting spree, they always want to take the guns away from the people who didn't do it. I sure as hell wouldn't want to live in a society where the only people allowed guns are the police and the military."
