Nottinghamshire Police is holding a fortnight long amnesty to appeal for the surrender of firearms and ammunition.
It is a decade since the last firearms amnesty in Nottinghamshire and the force is asking for people to surrender unlawfully held or unwanted guns and ammunition.
Officers said many firearms were held in innocence and ignorance of their illegality or were overlooked and forgotten in people's homes.
To provide members of the community with a safe place to dispose of any firearms or ammunition an amnesty is being held for two weeks from Monday 3 March.
During that period, those surrendering firearms will not face prosecution for the illegal possession and they can remain anonymous.
However, the history of each live weapon will be checked for evidence of its use in crimes.
Gun possession and gun crime in the county have both fallen by 37% and 34% respectively in the last five years.
Anyone handing in a firearm, or a stun gun, during the amnesty is advised to check the opening times of the 15 police stations participating in the amnesty and where possible phone 101 before travelling.
They will then be advised on how to best transport the weapon responsibly from home to the police station.
