PITTSBURGH, Pa. — A resident of West Mifflin, Pennsylvania, was sentenced in federal court on October 26, 2026, to 40 months of imprisonment, to be followed by three years of supervised release, on his conviction of possession of ammunition by a convicted felon, United States Attorney Troy Rivetti announced today.

United States District Judge Mark R. Hornak imposed the sentence on Davion Xavier Thompson, 23, who pleaded guilty to the charge in June 2026.

According to information presented to the Court, on January 23, 2026, Thompson knowingly possessed a Glock-style handgun with an extended magazine. Attached to the rear of the unserialized handgun was a machinegun conversion device, also known as a Glock switch. Thompson is prohibited from possessing both a firearm and ammunition as a result of prior felony convictions for carrying a firearm without a license and unlawful possession of a firearm.

Assistant United States Attorneys Kelly M. Locher and Nathaniel G. Ecker prosecuted this case on behalf of the government.

United States Attorney Rivetti commended the Federal Bureau of Investigation, Pennsylvania Office of Attorney General’s Narcotics Task Force, Allegheny County District Attorney’s Narcotics Enforcement Team (DANET), Stowe Township Police Department, and McKees Rocks Police Department for the investigation leading to the successful prosecution of Thompson.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the Department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.
