^^ Yeah, all you need to do is remove that rear pin. Be careful you properly align the trigger when re-inserting the pin, as that also uses the pin for alignment, and ensure that the slide release spring is properly located on top of the slide release when you re-position it before replacing the pin.
Then the LORD said to Cain, "Why are you angry? Why is your face downcast? If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at your door; it desires to have you, but you must master it." [Gen. 4:6-7]
