The widest hammer and trigger are referred to as “target” widths and the stocks that enclose the area behind the trigger guard and the front of the grip frame are targets. I believe the hammer and trigger widths were .500”.
At the time your gun was produced I believe the only stocks S&W was marketing were the Magna, the smaller stocks that follow the outline of the grip frame, and the Targets. Targets we’re standard on M29s
