Sizing

Wrap paper around the widest part of your index finger and measure. About 2.6 to 2.9 inches fits a standard frame; smaller wants a compact frame; larger or a wide palm wants the XL. Heavy pieces need a snug frame or they twist; light alloy is forgiving.

Texas changed its rules on knuckles in 2019 (House Bill 446). This page does not restate the statute and is not legal advice; the statute-cited write-up is the Texas knuckles statute guide on Self Defense Supply, and the state-by-state guide covers everywhere else. Knuckles are sold as paperweights and collectibles.
