The Elektropribor Company that manufactures the forward latching RPP guns and the "Wasp" models with a friction trigger have just announced a new gun in their "Shark" series, the "Mako Z55". The only details known so far are that it has a stainless steel 11 mm ID inner barrel and can shoot either 7 mm or 8 mm diameter spears. It can be fitted with a reel and I assume it is a floater after the shot. For now this is the only photo available.
