To dry-fire practice the DA/SA transition, shoot the DA shot, keep the trigger to the rear and rack the slide. As you are racking the slide, allow the trigger to reset and then take up the slack but keep contact with the trigger at all times. Fire the SA shot.
Works better with a partner who puts one hand behind your shooting shoulder to stabilize and works the slide for you after you break the DA shot.
Though a DA/SA does have 2 trigger pulls, it only has one reset point and that stays the same for every shot.
Prepping the trigger by letting it go to just the reset point (with constant finger contact) and taking up slack during recoil is a big key to the transition as well as fast and accurate shooting with any trigger.
