Felon Sentenced for Illegal Possession of Firearm After Offering To Sell Pistol, Illegal Switches for Gun Conversion

BILLINGS — A California felon who was identified offering to sell an undercover agent a pistol and switches used to convert guns from semi-automatic firearms to fully-automatic was sentenced today to two years in prison, to be followed by three years of supervised release, U. S. Attorney Jesse Laslovich said.

Drew Parker Seymour, 24, of Banning, California, pleaded guilty in February to prohibited person in possession of a firearm.

U.S. District Judge Susan P. Watters presided.

The government alleged in court documents that Seymour has been convicted of four felonies, including this case, that involve him illegally possessing firearms. In March 2022 in Billings, the Bureau of Alcohol, Tobacco, Firearms and Explosives learned that Seymour offered online to sell an individual illegal Glock switches, which are used to convert semi-automatic firearms into automatic machine guns. An undercover agent began communicating with Seymour, who offered to sell the agent Glock switches and a .45 caliber pistol. Seymour sent pictures of both. Seymour later withdrew his offer to sell the Glock switches. The undercover agent agreed to meet Seymour to buy the pistol. Before the meeting occurred, drug task force agents detained Seymour and his girlfriend at a post office in Billings as they attempted to pick up a package of fentanyl. In a search of the couple’s motel room, law enforcement located a .45-caliber, semi-automatic pistol hidden under a mattress. Seymour’s fingerprint was recovered from the gun’s magazine.

Assistant U.S. Attorney Benjamin D. Hargrove prosecuted the case. The Bureau of Alcohol, Tobacco, Firearms and Explosives, Billings Police Department, U.S. Postal Service and Eastern Montana High Intensity Drug Trafficking Area Task Force conducted the investigation.

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.
