There is a spare magazine in, can stow in the One also Reservemunitiun and 100 blue 6 mm balls.
Although one has to reload before each shot, but it is really fun and feel at Real. Also lets the Walther P99 secure with a switch.
It is really easy to use and has a stronger punch than I expected.
When I was shooting at fruit, the 6 mm balls were in the fruit, as I shot on thick cardboard flew the balls through round! Wow, that's so impressive that it almost scares me.
Just awesome!
