The Pump Pistol Accessories Kit is the perfect upgrade for your pumping needs. Watch the vacuum pressure gauge move as your pump brings you engorgement and heightened sensitivity. The accessory kit also includes body safe, non-porous silicone tubing. Plus, the silicone cock strap delivers lasting engorgement after your pumping session ends. The Performance Pump Pistol Kit is compatible and interchangeable with other Performance pumping cylinders and accessories.
