Convicted Felon Faces Federal Gun Charge After Allegedly Possessing ‘Giggle Switch’ Modified Glock

For Immediate Release
U.S. Attorney's Office, District of Columbia

            WASHINGTON – Robert Calvin Corbin III, 45, a four-time previously convicted felon from Washington D.C., has been indicted on a federal firearm charge as part of the “Make D.C. Safe Again” initiative. The indictment was announced by U.S. Attorney Edward R. Martin Jr., Special Agent in Charge Anthony Spotswood of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), and Chief Pamela Smith of the Metropolitan Police Department (MPD).

            Make D.C. Safe Again is a public safety initiative led by U.S. Attorney Martin that is surging resources to reduce violent crime in the District of Columbia. This initiative was created to address gun violence in the District, prioritize federal firearms violations, pursue tougher penalties for offenders, and seek detention for federal firearms violators.

            Corbin was indicted for unlawful possession of a firearm as a felon. On April 4, U.S. Magistrate Judge Matthew Sharbaugh ordered Corbin to be held pre-trial.

            According to court documents, police officers were called to investigate a report of a large group of individuals gambling with guns present near the 100 block of Q Street, NW. As the officers arrived at the scene, Corbin allegedly was smoking marijuana and drinking tequila from a plastic cup. An officer stopped Corbin for public consumption of marijuana and possession of an open container of alcohol. As the officer conducted a pat down, the officer felt a hard object in Corbin’s waistband and asked what the object was. Corbin responded, “nothing,” then allegedly attempted to shove the officer’s hands away and grabbed toward the officer. The officer and Corbin struggled. Police eventually cuffed Corbin.

            It is alleged that officers recovered a Glock 19 equipped with a laser sight and loaded with one bullet in the chamber and an additional 19 rounds in a large-capacity magazine. The firearm also had been modified with a “giggle switch,” a small device that converts a traditional handgun into a fully automatic machine gun. It is further alleged that during a search incident to arrest, police discovered a second large-capacity magazine with an additional 17 rounds of ammunition in Corbin’s bag.

            Corbin was placed under arrest for possession of a machine gun, carrying a pistol without a license, possession of unregistered ammunition, possession of an unregistered firearm, possession of a large capacity feeding device, felon in possession, and possession of an open container of alcohol. He is now charged in federal court with violation of 18 U.S.C. 922(g)(1) (Unlawful Possession of Firearm or Ammunition By a Person Convicted of a Crime Punishable by Imprisonment for a Term Exceeding One Year).

            The ATF and MPD are investigating this case. It is being prosecuted by Special Assistant U.S. Attorney Emily Reeder-Ricchetti.

           An indictment is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
