Officer Chris Kiszka stopped the gray Infiniti for having a headlight out -- commonly known as a "padiddle" -- among other infractions, shortly after 10 p.m. Thursday, Lt. James DePreta said.
Kiszka immediately detected the odor of pot in the car, then spotted what was a loaded, high-capacity 9mm magazine on the floor, DePreta said.
A subsequent search turned up a loaded 9mm handgun, marijuana and a digital scale, he said.
Rodger Purvis, 47, was taken into custody with the assistance of Sgt. Jared Shatkin.
He was charged with several weapons and drug offenses, including being a convicted felon in possession of a firearm.
Purvis was sent to the Bergen County Jail and remained there Friday awaiting a first appearance in Central Judicial Processing Court.
Police Chief Dean Pinto commended his officers for “safely removing another illegally owned and possessed firearm from the streets."
