The amnesty between November 3 and 14 gave people the chance to take their unused and unwanted weapons, including revolvers, pistols, rifles and shotguns, to police stations in Boston, Grantham, Lincoln and Skegness.
A Lincolnshire Police spokesman said a “steady flow” of weapons were handed in throughout the county as people took advantage of the amnesty, without fear of prosecution.
Chief Inspector Phil Baker said: “We are happy that people have made the most of the opportunity to hand in 132 of these weapons, a significant number to have removed from circulation.
“Lincolnshire is a rural farming county so there are many reasons why people may have firearms in their possession.
“What is encouraging though is the fact that the amnesty has made people think about whether they need to hold on to these weapons and whether they have the legal right to do so.
“Having 132 fewer firearms within the county means that there are 132 less opportunities for them to be used for criminal activity.”
Figures from Lincolnshire Police showed that between April 2013 and March 2014, only 18 weapons had been lost or stolen compared with a figure of almost 580 in England and Wales.
Anyone who still holds an unwanted or illegal firearm can hand it in and it will be dealt with according to the appropriate circumstances.
