For whatever reason, my High Speed slingshots are not making sounds although they work fine. I've never had this happen on any other pin, and far as I know, slings do not have a separate switch to trigger sounds/scoring. Is there anything I can check? I'm at a loss!

Haha, you are correct! Right after I posted this, I went down to doublecheck, and sure enough, there were the switches. Seems like there is a paper spacer between the blades with a hole cutout for the contacts. The paper was warped, and not allowing contact, so I removed it, and all is well now. Is there a need for that paper there?

Thanks for the info, they are adjusted fine now, so I removed the paper spacers from both.
