TRUMARKS No.S9 slingshot’s plastic handle slides up and down the U-shaped Aluminum Frame. When pushed up, the chamber releases SA30 ammo from a capless hole in the bottom. When pushed down, the hole becomes "self-sealing" and traps ammo in the handle. 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 slingshot has matched-pull latex RR-1 Powerbands with soft split-leather pouch.
