Two men were shot, one of them an innocent bystander, during a dispute outside a Manhattan pizza shop Sunday morning, cops said.

One of the men in the fight whipped out a gun at Stanton Street and Ludlow Street on the Lower East Side around 4:15 a.m. and blasted his rival in the groin, according to police.

A stray bullet struck a third man, who was nearby working at a “licensed establishment,” in the left leg, a police spokesman said. It wasn’t clear where the man was working.

The victims were taken to Bellevue Hospital in stable condition.

The shooter, who was described as standing 6-foot-2 and wearing all gray, fled, cops said.
