Speargun trigger mechanism

A grip assembly for a fishing speargun, comprising:

• a grip housing having a handle, a trigger assembly removably received in the grip housing with a frame, said frame having guide means for receiving the proximal end of a spearpoint shaft, a trigger pivotally mounted in the trigger frame, a latch bar pivotally mounted in the frame having a set position and a reset projection engageable by the spearpoint shaft proximal end as the shaft is inserted into the frame guide means, said latch bar also having a pawl when in its set position engageable with the shaft proximal end for holding the shaft in a set position in the guide means against the force of firing bands pulling on the shaft, said trigger being selectively operable to hold the latch bar in its set position and to release the latch bar as the trigger is pulled, a pivotal safety pawl selectively engageable with one of the trigger and latch bar to selectively prevent movement of the latch bar from its set position, and a pivotal operator for the safety pawl positioned outside the grip housing having a radially extending projection constructed to be operated by the fisherman's trigger hand while on the grip handle, the safety operator radial projection having an "on" position generally transverse to the spearpoint shaft and an "off" position generally parallel to the spearpoint shaft.
