Sure sounds like the Ball In Hand switch. Inside the glove's big magnet ring is a leaf switch. Over time and impacts, the leaf gets bent back and won't register a catch.
Reach up in there with your finger and see if it will trip in Switch Test mode. If it does, just bend the leaf downward some. If you can feel the click of the switch, but it doesn't register, you may have a loose wire, or possibly something in the switch matrix....
Good luck!
