The gun was seized Thursday morning.
Two people are charged after an investigation by the Windsor Police Drugs and Guns Unit.
Officers were involved in a drug trafficking investigation that also centred around a male who was in possession of a firearm while actively dealing crack cocaine. Officers stopped a vehicle and seized a loaded 6 shot .22 calibre revolver handgun. Nathaniel Campbell, 31, of Ajax and Charles Foster, 28, of Windsor are both charged with possession of a restricted firearm without licence.
