Curtis Cheng's Son at Gun Control Rally

THE NSW widow of a man shot dead in a robbery has made an emotional appeal to the Turnbull government to ban a new rapid-fire shotgun.

Mary Cusumano, whose husband was killed 20 years ago, has joined a small group of anti-gun activists in Sydney to push for a ban on the Adler A110 shotgun, which has bypassed laws on semiautomatic weapon restrictions.

“We need to protect people in this country,” she told reporters at NSW Parliament on Thursday.

The son of murdered NSW Police accountant Curtis Cheng was scheduled to attend but was unable to be there, the head of the Homicide Victims support told AAP.

Gun Control Australia chair Samantha Lee says lever-action shotguns have been classified as Category A because they are single shot, while the Adler A110 features a magazine and can shoot five shots in five seconds.

The shotgun had been approved to enter the country until the Federal Government placed a ban on its sale, which was lifted in August.

The firearm is undergoing a review of its categorisation, but anti-gun activists are pushing for severe restrictions as the next best option after a ban.

“There’s a big question mark over whether this should be let in at all,” state Labor MP Hugh McDermott said.

“If it is let in, it has to be restricted to a class D, or class C licence.”
