Character mistake: When they are at the docks/harbor and they capture the person who poisoned the guy that hired Magnum, Higgins tells him if he resists, Magnum will shoot him. She says he has 16 bullets, but he's carrying a 1911 and the most it will have is 10 rounds.

The Day Danger Walked In - S3-E5
Factual error: Higgins, Thomas, TC and Rick are locked in a freezer. Their barber friend is tapping his horn in "a pattern" Higgins says is Morse code, and announces that he tapped "move back." Not really. I know Morse Code. All I got (along with a few undecipherable things) was TOERT NMU ETM CEA OFJ DER WK. No way that spells "Move Back."
Thomas Magnum: My father once said that being brave doesn't mean not being scared. It just means you've decided there's something more important than your fear. (00:22:20)
Trivia: The original TC, Roger E. Mosley, shows up in 2 episodes in the series. The first is S1-E18 - A Kiss Before Dying and the other is in S3-E5 The Day Danger Walked In.
