A woman was busted on a Manhattan train early Saturday after straphangers spotted her with what looked like a gun inside a holster and a pair of handcuffs, cops said.

Fellow straphangers on the northbound 6 train with Shakira De La Cruz, 22, called police, who found Cruz with an air pistol as well as a pair of handcuffs affixed to her belt, authorities said.

She was also yelling and making noise, police said.

Arriving cops took De La Cruz, who was also wearing headphones, into custody at the 125th Street station.

She was charged with criminal possession of a weapon, as well as a local law violation for carrying the handcuffs, according to police.
