There’s another gun out on the city streets — thanks this bozo retired cop.

Former NYPD Detective Eric Reynolds put his Colt. 38 on a sink in an East Village bar bathroom so he could throw up in the stall — then stumbled out wasted without the weapon.

By the time he realized his mistake and went back in, the six-shooter was gone — and now he has a raging NYPD to deal with.

Reynolds, who posts images of himself wielding guns on Facebook — including a movie poster that says “Bad Detective” — spent nearly six hours drinking at the gay Phoenix NYC bar on East 13th Street starting at 8 p.m. Tuesday, sources said.

The boozing caught up with the cop-turned-stand-up comedian and he went to the bathroom.

Reynolds placed his cellphone and pistol on the sink while worshipping the porcelain god, picking only the phone back up when he took off at around 1:30 a.m. Wednesday, the sources said.

He and a buddy had made it all the way to Union Square when Reynolds patted his gun holster and realized his epic mistake.

The retiree sprinted back to the watering hole only to find that someone had stolen the weapon. He called police to report the lost pistol and told cops he “was not feeling well,” the sources said.

Cops are checking surveillance-camera footage to find the thief, and the NYPD’s Internal Affairs Bureau was notified.

Reynolds has not been charged with a crime for misplacing the weapon, cops said.

An owner of Phoenix NYC was forgiving.

“We all make mistakes. Maybe he had been drinking. He made a mistake,” said the woman, who would not give her name. “Maybe he shouldn’t have brought a gun with him.”

Reynolds served two decades with the NYPD, including at the 49th Precinct in Eastchester section of The Bronx.

He calls himself a working “comedian” on his Facebook page and was the subject of an interview on a comedy podcast.

An online description of the episode of “Offstage with Christian Polanco” says: “Eric spent many years arresting bad guys, now he’s telling jokes on stage.”

His Facebook page features a poster for the 1992 movie “Bad Lieutanant” with his face superimposed over star Harvey Keitel’s and the word “Lieutenant” replaced with “Detective”

The former cop is dressed as a nun in one photo and playing with his Chihuahua in others.

Reynolds also put on the site a Post front-page photo that shows him with a suspect in the Puerto Rican Day Parade.

Reached at home, he answered the door with his Chihuahua and declined to comment.
