A method of reversing a latch bolt within a case of a mortise lock, wherein the latch bolt comprises a bolt head operatively coupled to a latch tail, wherein the latch tail is operatively coupled to a tail plate, and wherein the latch bolt further comprises a reversibility assembly, wherein the reversibility assembly comprises a catch operatively coupled to the tail plate, a catch biasing member operatively coupled to the catch, a restraint member operatively coupled to the catch, and a restraint biasing member operatively coupled to the restraint member, wherein the catch is moveable between an engaged position and a disengaged position through the catch biasing member, wherein the restraint member is moveable between an activated position and a deactivated position, wherein when the catch is in the engaged position the restraint member is in the deactivated position and the latch tail is operatively coupled to the tail plate, and wherein when the catch is in the disengaged position the restraint member is in the activated position and the latch tail is removable from the tail plate, and wherein the method comprises:
disengaging the latch tail from the tail plate, while the latch bolt is within a casing by disengaging the catch and activating the restraint member;
removing the bolt head or the latch tail from the case in a first position;
rotating the bolt head or the latch tail to a second position that is different from the first position;
