Gqeberha firearms dealer Karen Webb and her co-accused appeared briefly in the city's Magistrates Court on Tuesday.
It was the first time that Webb and Francois van Der Merwe appeared side by side in the dock.
Both accused face a string of charges relating to the Firearms Control Act.
Since Webb's arrest in February, numerous counts have been added to her charge sheet.
The long list of existing charges includes theft, conspiracy to smuggle firearms, fraud, the unlicensed trading of firearms, providing firearms and ammunition to persons who are not allowed to possess them, and defeating the ends of justice.
Her arrest on 8 February forms part of an ongoing police investigation into how firearms got into the possession of gangsters in the city's northern areas and other provinces.
The theft charge relates to ten 9mm Glock pistols that went missing from the Aquila Arms’ stock while the cache was stored at her premises.
Van Der Merwe was arrested in George in September.
He is charged with the transportation of firearms throughout South Africa without an in-transit permit, failure to ensure that the firearms and ammunition possessed on the authority of the dealer's license were transported in accordance with the packaging requirements during transportation as set out in the regulations, the unlawful possession of a firearm, and the unlawful possession of ammunition.
Van Der Merwe allegedly transported a total of 658 firearms from Webb's cache to the Western Cape over two days in January.
According to the charge sheet, the firearms were transported from Webb's Arms to Pete's Gun Repairs in Sedgefield.
At the time, Webb was allegedly already the subject of a police investigation.
A decision is yet to be taken on whether the trial will be heard in the regional court or in the city's high court.
Van Der Merwe is out on bail while Webb will remain behind bars pending the finalisation of the trial.
The case was postponed to 28 January next year.
