An NYPD officer has been charged with pointing his gun at two waitresses during a boozy night out with his sergeant at a Queens karaoke lounge, The Post has learned.

Hyun Kim, 25, and Sgt. Jung Kim went to the Crocheron Avenue bar, the name of which was unavailable, Tuesday night after getting off work at the 115th Precinct in Jackson Heights, police sources said.

One of the waitresses eyed the cop’s weapon, and asked if he was a “gangster,” the sources said.

“No, I’m a cop and this is my boss,” Hyun Kim allegedly ­responded.

The sources said he then pulled out the weapon and racked it, dropping the magazine and scattering bullets on the ground in the process. Then, Hyun Kim, who’s believed to have been drinking, allegedly pointed the firearm at the waitress, the sources said.

Startled, she rushed to report the incident to her boss.

When the manager came out to talk with the two cops, Hyun Kim was allegedly aiming at the head of another waitress.

The two Kims argued with the owner and eventually agreed to take off, the sources said.

The sources said surveillance footage shows they left behind the magazine and bullets.

One of the waitresses and manager reported the incident at the precinct station house.

Hyun Kim — who’s due to earn $52,030 with the NYPD this year, according to public records — was arrested Saturday afternoon. He was charged with two counts of menacing, the NYPD confirmed Sunday.

He was given a desk appearance ticket and will be in court Oct. 28 for an arraignment hearing, said a spokeswoman for the Queens District Attorney’s Office.

Both Hyun Kim and the sergeant — who makes $118,715 a year, according to public records — were suspended without pay, according to police and sources.

A worker at one area sing-a-long bar said he’d never heard of anything like that happening in the area before and called the incident “a very serious problem.”

“I want to know why they pointed their gun at the waitress, why was the reason for that?” said J.H. Lim, who works at Flower Karaoke. “It doesn’t make sense if your life isn’t in danger, why pull out your gun?”
