what exactly is the point of a hybrid speargun ?
It allows use of a good stand alone trigger mechanism with a pipe. I see no other advantage. The "more mass to absorb recoil" idea simply doesn't work, as the mass is at the back of the gun not at the front where it's needed to control muzzle lift. People get the hybrids thinking they can add more band power, and the gun ends up shooting erratically. To shoot decent they need to be powered just like a pipe gun. Nowadays there are production pipe guns with good full stainless steel triggers, so the hybrid is obsolete IMO. They look pretty and allow for some creativity in the building of the gun, that's about it. If someone likes how something looks, they'll find all the theoretical reasons necessary to convince themselves why it's the ultimate solution to their spearfishing needs.
