Are your bands hitting your hand after the shot? We can help with that!
Are the bands hitting you in the knuckles when the shot is let off? This can be avoided, and yes, it can be painful and irritating.
Hand slap is the result of the bands being too powerful for the projectile and is most common when the bands are mounted in the OTT or 'Over the Top' orientation.
This is easy to fix! Either lengthen your bands, shoot a heavier projectile, or shoot lighter weight bands. Hand slap happens when the bands cannot transfer their energy into the projectile efficiently. If the ammo is too light or the bands are too heavy, the bands travel forward of the slingshot frame and then retract back into your hand. Check out the following videos:
