1. A trigger assembly for a crossbow, the trigger assembly comprising:
- (a) a string retainer moveable between a firing retainer position and a non-firing retainer position, wherein the retainer is (i) arranged in the non-firing retainer position to retain a drawn bowstring of the crossbow and (ii) arranged in the firing retainer position to release the bowstring;
(b) a trigger mechanism moveable between a firing trigger arrangement and a non-firing trigger arrangement, wherein the trigger mechanism is (i) arranged in the non-firing trigger arrangement to hold the retainer in the non-firing retainer position and (ii) arranged in the firing trigger arrangement to enable the retainer to move to the retainer firing position;
(c) a primary safety mechanism moveable between a primary safety-off arrangement and a primary safety-on arrangement, wherein the primary safety mechanism is (i) arranged in the primary safety-on arrangement so as to block movement of the trigger mechanism into the firing trigger arrangement and (ii) arranged in the primary safety-off arrangement so as to allow movement of the trigger mechanism into the firing trigger arrangement; and
(d) a removable secondary safety mechanism arranged to be coupled to the trigger assembly in a secondary safety-on arrangement (i) so as to block movement of the primary safety mechanism from the primary safety-on arrangement to the primary safety-off arrangement or (ii) so as to block movement of the retainer from the non-firing retainer position to the firing retainer position both with and without a bolt loaded onto the crossbow.
