They were hosting a 2 wek amnesty, which ended earlier this month
The 38 firearms firearms included an AK-47 assault rifle and a James Bond style Walther PPK pistol (pictured), as well as shotguns, air rifles and 1172 rounds of live ammunition.
The national surrender ran from two weeks from July 20th to August 4th.
Inspector Nigel Barraclough from Lancashire Constabulary’s Tactical Operations department said: “The surrender was a great success and even one less firearm on the streets is one less that could be used by a criminal to harm or threaten our communities
"Our aim is to keep Lancashire safe which we will continue to do by working with partners and our local communities to prevent and detect crime.
“This nationwide surrender is a very good example of how members of the public can directly help us prevent harm to our local communities by removing the risk of weapons getting into the wrong hands.”
Clive Grunshaw, Lancashire's Police and Crime Commissioner said: "It is great that this campaign to remove dangerous firearms from our streets has seen a number of these dangerous weapons handed in to officers.
"Every single firearm handed in is one which will not be able to fall into the wrong hands and the public's support is crucial. There are number of reasons that people may find themselves with a firearm they should not have, potentially through inheritance or legally owned guns they have no more use for.
"Tackling violent crime is a key priority for us and this is just part of the work that goes on in the county to make our communities and the people of Lancashire safer."
