It Takes a Thief (1968)

A Sour Note - S2-E2

Factual error: Gino commits a murder using a six-shooter with a silencer attached, and his shot doesn't make any noise. But it should have. Though it's a long-standing Hollywood cliché, a revolver with a silencer wouldn't be silent at all. Unlike automatic weapons, revolvers are open-chambered, which allows sound to escape. They can't be muffled with a silencer. (00:34:00)

Factual error: Penny hides the stolen microdot on her contact lens, a re-hashed spy plot (used 5 years earlier on "The Man From U.N.C.L.E.") that wouldn't work. Any foreign object attached to your contact lens would feel like a shard of glass in your eye. (00:42:00)
