Andre speargun handle

I haven't tried this handle. The difficult point with this type of handle configuration is whether the trigger slot matches your trigger mechanism as far as range of movement and/or space available inside the trigger guard. The trigger itself can sometimes be cut if the trigger guard is too shallow. But that may affect the trigger pull.

In general I'm not a fan of heavily contoured speargun handles, because you can only shoot the gun in the straight forward position.
