In accordance with the current invention, a needle-free injection system includes a cap that has a first seal for sealing an injection orifice when the cap is engaged with an injection end of the system. The cap also includes a push-rod for facilitating priming of the system when engaged with a priming end of the system. The system also includes a push-rod engaging mechanism disposed at the priming end of the system for receiving the push-rod for priming the system. The system further includes a gas cylinder for supplying pressurized gas for injecting, via the injection orifice, an injectate initially disposed within a storage chamber, and a sealing system for preventing the pressurized gas from ejecting the injectate from the system prior to actuation of the system. Actuation of the system is achieved via a slidable trigger plate.
