PFD
Any SxS needs two triggers be it a rifle or shotgun. They built single triggers for those too uncoordinated to use two triggers, or those two slow to remember to move their trigger finger to the second trigger or those too slow to count to two.
Just like pump guns had to be replaced by autos for those too dumb to shoot them sisngle triggers had to be invented for you know who. You know how hard it is for some to learn, bang...shuck...bang...shuck...Mark.
Instead you hear, bangbangbang, damm it, Mark.
