Police are urging people in South Yorkshire to hand in guns and ammunition to avoid prosecution as part of a nationwide amnesty.
The force is holding a two-week firearms surrender starting on Saturday.
Anyone with weapons can hand them in at police stations across the area and will not face action – even if they held them illegally – unless the item is found to have been used in a crime.
Police say people with firearms often don't realise the laws governing possession.
Detective Inspector Marie Bulmer said: “When a gun falls into the wrong hands the damage can be devastating and life-long. This is your chance to help make sure there are less weapons on our streets.
“I urge anyone who has a firearm being kept illegally to hand it in to your nearest police station, this can be done anonymously."
