Mom & kids duck a bullet

A gangbanger out on bail after a firearms bust allegedly exchanged gunfire with a rival in Manhattan — forcing a family to take cover in their apartment when a stray bullet smashed through their window, police sources said.

A Harlem resident and her two children managed to escape harm as Joshua Moreno, 20, allegedly fired off the shots at 9:45 p.m. Thursday outside the Amsterdam Avenue home, the sources said.

Moreno fired six rounds and ran off, the sources said. Cops soon captured him and found a Jennings .25-caliber pistol he had allegedly ditched, sources said.
