Pursuit Marketing Inc. (PMI) Piranha Short Barrel pump.  The Piranha series were the first "from the factory" pumps produced by PMI with a soldered direct feed. Internally, this model operates on the same Sheridan-based system as PMI's other pumps like the PGP, PMI-1, and KP rifles. This one was purchased in the early '90s and has PMI's Turbo valve installed, aftermarket grips, a Daisy point sight, and an AGD (Air Gun Designs) Micro CA II lever activated 12-gram quick changer. PMI also produced a Long Barrel version of the gun which featured a longer barrel and pump handle.
