Narrative:

I was pilot flying on turn to final over FAF for the runway. Aircraft overshot and I was correcting back to course; speed was set to flaps 40 target while still at flaps 15 airspeed aircraft 'airspeed' alert sounded as I corrected back to line up on final I looked down and saw airspeed at 138 as it approached the first red dot on the mach air speed indicator; I pushed the thrust levers forward and leveled the aircraft as the stick shaker momentarily shook the column. After aircraft accelerated back on speed; I called for landing flaps 40 and flew the remainder of the approach to landing uneventfully.
