A routine traffic stop in Richmond's southern district last Thursday turned into something far more serious when officers say they pulled four illegal firearms out of a single vehicle. Police report that three of those guns had been modified to fire fully automatically. Officers also located numerous extended magazines and one firearm that had been reported stolen.
According to a post from the Richmond Police Department, the department shared photos of the seized weapons and confirmed that the stop took place last Thursday. The post did not immediately list arrests or charges and offered only limited additional details, so for now the department is keeping the finer points close to the vest.
What Officers Say They Found
Police describe the guns as illegally modified and dangerous, with three converted to allow continuous fire with a single trigger pull. Federal authorities treat conversion parts as machine guns, and the Bureau of Alcohol, Tobacco, Firearms, and Explosives has pursued cases targeting the sale and trafficking of so-called "Glock switches" and similar conversion devices. The ATF has used press releases and prosecutions to warn about those parts.
Where This Fits Locally
Seizures of illegal or modified weapons during traffic stops have been popping up across the East Bay in recent months. One recent example is a Hercules case in which officers swept 13 illegal guns off city streets. The California Department of Justice's APPS program also tracks removals of firearms from people who become prohibited, and the DOJ's recent APPS report documents thousands of recoveries statewide, per Hoodline.
Legal Implications
Possessing a machine gun or a conversion device can carry federal felony penalties, and California law also outlaws certain automatic and unregistered weapons. Penal Code section 12280, detailed by Justia, outlines state prohibitions, while federal statutes and ATF guidance treat many conversion parts as machine guns for enforcement purposes.
Richmond police said the investigation is ongoing and that more information will be released as it becomes available, according to the department's Facebook post. The post and the photos are publicly viewable on the Richmond Police Department's Facebook page.
