Hamilton man pleads guilty to illegally possessing firearms, Glock switch

CINCINNATI - A previously convicted felon pleaded guilty in U.S. District Court to illegally possessing firearms, including a fully automatic weapon.

Justin Ervin, 35, of Hamilton, admitted to possessing a machinegun-conversion device, known as a switch. The device converts a semi-automatic weapon into a fully automatic weapon.

Ervin's plea agreement includes a recommended sentence of 60 months in prison.

According to court documents, in May 2024, Hamilton police officers executed a search warrant at a residence in which Ervin had been living. Officers were originally called to the house in response to a strangulation incident, for which Ervin has pleaded guilty in state court. Officers discovered seven firearms, one conversion device and more than 2,000 rounds of ammunition at the residence.

As a previously convicted felon for robbery and arson, Ervin is prohibited from possessing firearms and ammunition.

Ervin was indicted by a federal grand jury and arrested in June 2024.

Kenneth L. Parker, United States Attorney for the Southern District of Ohio; Daryl S. McCormick, Special Agent in Charge, U.S. Bureau of Alcohol, Tobacco, Firearms & Explosives; and Hamilton Police Chief Trent Chenowith announced the guilty plea entered on Oct. 30 before U.S. District Judge Douglas R. Cole. Assistant United States Attorney Ryan A. Keefe and Criminal Chief Christy L. Muncy are representing the United States in this case.
