I've seen that guy pop up in my recommendations before, and he is a beast. I kind of feel like using a slingshot (a normal one that can be obtained easily) in an active situation would be awkward if you have zero practice with one.

I'm sort of leaning towards the less lethal ball options because at least I have some limited experience shooting pistols, unlike drawing and aiming a slingshot in a high adrenaline situation.

The only problem is that, like everything else online, half of the reviews say that the paintball options work great and the other half say they are ineffective, unreliable, and inaccurate. I can vouch for the last one somewhat, having fired rubber practice rounds through a pistol marker. They fly very unpredictably and with limited velocity compared to normal balls. I'd guess a hard less lethal round or one filled with powder would do the same thing.

Can you fire those same type of projectiles (SALT, etc) with a sling, and are they any faster or more accurate that way?
