Alfsauve, I just noticed that your M&P is a pure Model of 1905 with no engineering changes. The company made only about 10,000 of these before introducing the internal modifications that define the First Change, including the trigger rebound slide that still exists in S&W revolvers today. In your gun, the trigger return was managed by a separate flat spring in the grip that drove a pivoting arm. You can see on the left side of your gun that the stud for the trigger return mechanism is directly below the thumb release near the trigger guard's rear junction point with the frame. In the First Change design, the trigger return spring stud is below and behind the thumb release, closer to the top of the grip frame cuts. Check the left side of the 1905/First that I show in post no. 115 in this thread.
