BLACKTOWN police recently destroyed some captured firearms, seized or surrendered in many operations over many months.
"These guns were seized in more than 100 operations over the last 12 to 18 months," Blacktown police commander Bob Fitzgerald said.
"They were seized in the course of arrests, surrendered or retrieved from deceased estates."
The announcement provoked some hostile comments on the command's Facebook page, by people who believed keeping firearms was an inalienable right.
But Inspector Fitzgerald said it was better to destroy these firearms than allow for the possibility of the wrong hands getting hold of them.
The Blacktown operations supported the NSW Police's statewide push to get rid of illegal firearms, Operation Unification.
It was officially launched in June, with police commanders around NSW appealing to people for information about such weapons.
Inspector Fitzgerald also advised people about how to dispose of firearms.
"You may only dispose of a firearm through a licensed firearms dealer or by unconditional surrender to police," he said.
"A person who comes into possession of a firearm, but is not authorised by or under the act to possess the firearm, must immediately surrender it to a police officer."
He advised against people taking
firearms into a police station unannounced.
"It is a good practice, when surrendering a firearm, to please contact us prior to walking into the station," Inspector Fitzgerald said.
He also warned people in possession of unauthorised firearms could face heavy fines or even jail time.
