Great eye, yes the grip is based on a P99, it even has a weighted magazine for ballasting the gun. No, it is not actually from a P99 I made a mold of one, cast it in plaster then had to trick it out so it would work as a speargun grip,then made another mold of that,then cast it out of high strength polymer. I chose the P99 because of how comfortable it is in my hand.
