Had the same issue on one of my prodigy’s but with the Brazos Pro Tuned trigger kit, would get the occasional hammer follow when trying to go really fast. The trigger pull was about 1.5lbs, called Bob at Brazos and he informed that the trigger pull was probably to light and should be set around 2.5lbs, I bent the left sear spring leg, set the trigger to just over 2lb. Now have close to 1k down range since and no more intermittent hammer follow.
