A routine traffic stop in Spring turned into a weapons and warrants bust on Monday, when Harris County Constable Precinct 4 deputies pulled over a driver in the 6000 block of FM 2920 and discovered he was wanted on multiple warrants and carrying what they say was an illegally modified handgun. The adult male was arrested at the scene and transported for booking.
According to a Facebook update from Mark Herman, Harris County Constable Precinct 4, Deputy Gallardo initiated the traffic stop and took the man into custody after a records check. The post states that deputies found two open warrants, one out of Montgomery County for larceny and another from the Harris County Sheriff’s Office for theft, and recovered a handgun that the office says had been modified to function as a fully automatic weapon.
What deputies found
Precinct 4 reported that the seized firearm had been altered so it could fire in a fully automatic mode, the kind of conversion that federal authorities treat as especially high risk. Under federal law, devices that convert semiautomatic pistols into fully automatic weapons, often called “Glock switches” or conversion devices, are classified as machine guns, and simply possessing those parts can trigger federal charges, as outlined by the Bureau of Alcohol, Tobacco, Firearms and Explosives.
Local enforcement pattern
Constable Herman’s office has been leaning on traffic stops along FM 2920 to pick up wanted suspects and seize contraband, a trend that has been hard to miss in both local coverage and the precinct’s social feeds. A recent look at an earlier FM 2920 warrant stop highlighted how often deputies in the area are using routine pulls to reel in people with outstanding cases.
Potential charges and next steps
It remains unclear whether federal authorities will open a parallel case in this latest arrest, although prosecutors sometimes bring federal counts when handgun conversion devices are involved. The precinct’s Facebook post also urged residents to keep an eye on its social media channels and to download the “C4 Now” mobile app for more updates on the arrest, per Mark Herman, Harris County Constable Precinct 4.
