Shaquille O'Neal went 52.7% from the charity stripe during his NBA career, but he's a much better shooter with a gun in his hand ... 'cause the Hall of Famer was a stone-cold killer while filming scenes for a TV show!!
As we previously reported, the Big Aristotle has become a familiar face on set of the "Gravesend" mob drama recently ... landing a role after gushing to director/star William DeMeo about his love for the first two seasons of the Prime Video project.

Apparently at some point in the show, 53-year-old Shaq's "Mustafa" character gets REALLY pissed off .
