A routine traffic stop in St. Louis’ District 4 on Wednesday briefly turned into a foot chase and ended with officers hauling in two guns outfitted with machine gun conversion devices, along with suspected narcotics and cash. The incident was summarized in a short post on the St. Louis Metropolitan Police Department’s official social channels, where the department highlighted the work of District 4 officers and tied the stop to its broader public-safety push.
According to St. Louis Metropolitan Police Department (OFFICIAL), officers pulled a vehicle over on Wednesday, at least one person took off on foot, and a brief pursuit followed. When it was over, police said they had recovered the firearms, suspected drugs and cash, crediting District 4 officers for the seizure and emphasizing their commitment to keeping weapons like these off city streets.
What Officers Say They Pulled From the Car
Police reported that the two handguns were equipped with machine gun conversion devices, small parts that can turn a semiautomatic pistol into a fully automatic weapon. As outlined by the ATF, those conversion devices are treated as machine guns under federal law. The agency says it has recovered more than 31,000 of these parts in recent years, a number that gives some context to why local officers keep flagging them in public posts.
Part of a Growing Pattern in North St. Louis
The latest haul fits a pattern District 4 patrol officers have been seeing on their beats. In May, a separate traffic stop in the Jeff-Vander-Lou area turned up pistols fitted with auto-sear switches in the hands of teenagers. That incident, involving three armed teens, also ended with officers credited for getting switch-equipped weapons off the street.
Like those earlier cases, the department’s latest post framed the seizure as part of a broader effort to clamp down on rapid-fire weapons showing up in neighborhood conflicts.
Legal Heat for Conversion Devices
Federal law treats these conversion devices as full-fledged machine guns, and simply possessing one can bring a felony case with serious prison time, the ATF warns.
Prosecutors in the Eastern District of Missouri have already leaned on those statutes in St. Louis. The U.S. Attorney’s Office reported that a local defendant pleaded guilty in March after being found with guns equipped with machine gun conversion devices on multiple occasions.
In its Facebook update on Wednesday’s stop, the department said officers remain focused on “investing in safety and building a safer St. Louis for all,” and again credited District 4 officers with the latest recoveries. The post did not include any information about arrests or charges, according to St. Louis Metropolitan Police Department (OFFICIAL).
