When pushed down, the handle becomes "self-sealing" and traps the ammo again. The S9 slingshot fits in a back pocket. It has a moderate pull, and can be accurately shot using the "intuitive method" of sighting. The S9 slingshot will store SA30 5/16"steel-balls in the handle. Ammo is not included, and must be purchased separately. The S9 slingshot has matched-pull latex RR-1 Powerbands with asoft, split-leather pouch.
