[edit] Summary

This is a close-up of a .40 S&W Beretta PX4 Storm showing a side view of the barrel with it's locking "shoulder" appearing as a square peg in a round hole. A cam slot in the bottom portion of this barrel feature rotates the barrel via a cam tooth in the composite locking block that interfaces both the frame and the slide. Torque from the barrel's 6R rifling augments the cam tooth in rotating the barrel 45 degrees counter-clockwise to unlock the slide from the barrel.
