The slotted hammer is for the late run kp-3's I believe. The slot is for a guide rod coming from the base (trigger assem.) to keep hammer from turning. I am thinking that if slot in hammer rotates to the bottom the sear may not catch. Melkson's first round enabled kp uses that type of trigger assembly. See in holligans horde section.
