The Smith & Wesson Sting Ring Stun Device Keyring (brand part no. UZISG18KRING) packs an electronic stun device into a compact ring-and-keyring form factor built for everyday carry. Rather than a bulky handheld unit, it attaches directly to a keychain, so it rides along with house and car keys instead of taking up space in a bag or pocket on its own. As an electronic contact stun device rather than a spray or chemical deterrent, it delivers its effect through direct contact rather than an aerosol cloud that can drift back toward the user. It is a federally legal consumer personal-safety product, sold nationally with no license, registration, or dealer transfer required in most states. The compact size and keyring attachment make it easy to keep within reach on a nightly walk, a solo commute, or any other situation where having personal safety gear on hand matters.
