Scottish police have launched a two-week gun amnesty to stop firearms falling into the hands of criminals.
They hope its firearms surrender campaign will reduce the risk of weapons falling into the wrong hands.
Assistant Chief Constable Bernard Higgins said: "What we want to do is remove any firearm availability from the criminals that operate right across the country.
"There have been a lot of high profile incidents in recent times and we want to reduce the opportunity for individuals that are intent on using firearms within our communities to actually come into possession of these weapons.
"The people that will discharge firearms within the criminal world show an utter disregard for the safety of our communities and the safety of our citizens, so one of the things this surrender campaign hopes to achieve is actually to remove a whole bunch of weapons that if they fell into the wrong hands could do significant harm."
People will also be able to hand in replica firearms, air weapons, BB guns, imitation firearms, component parts and other ballistic items during the initiative.
Anyone who surrenders a firearm will not be asked to give their personal details - but police said that they reserve the right to investigate the history of the weapon if appropriate, to establish whether it has been used in any crime.
People can hand in any firearms, whether someone has realised their firearms licence has expired, has unexpectedly discovered a gun while clearing out a house, or decides they no longer want to keep a lawfully held firearm.
Police have no idea how many weapons may be handed in, though they say it is unlikely to be anywhere near as high as other gun amnesties. Last year in Australia, some 51,000 firearms were handed to police.
Lord Advocate James Wolffe QC said: "Anybody surrendering a firearm or other relevant item during Police Scotland's two-week campaign will not be prosecuted for simple possession of the item.
"The immunity only applies to handover of the weapon and not to any other offence it may be linked to after examination."
Justice Secretary Michael Matheson welcomed the amnesty.
He said: "Firearms offences are at historically low levels in Scotland. Nonetheless, there is always a risk that unused or unlicensed firearms could fall into the wrong hands.
"I therefore welcome Police Scotland's campaign to remove unwanted weapons from our communities, and would urge anyone who has a firearm that they have no good reason for keeping to take this opportunity to safely surrender it to the police."
