This might be a no brainer for some people, but I've searched and can't find any info about this online. I've seen tons of videos with divers holding the speargun on the shaft, with their hand wrapped around the rubber. I mostly see this when they're diving down for comfort and maneuverability I guess. If the rubbers are loaded and taught, doesn't putting your hand there risk setting it off? They're only held by the wishbone on the notch and I never put my hand there for fear of it snapping and catching my finger or something.
