The surrender began on July 20 and ended last Sunday, which saw an array of firearms handed in.
Police in Barnsley opted for a ‘no questions asked’ approach, with anyone handing in a weapon allowed to do so anonymously, which saw a total of 67 handed in across the period.
Detective Inspector Marie Bulmer said: “The success of the surrender is testament to our communities and their willingness to protect their neighbours, family and friends and make South Yorkshire a safer place.
“I would like to thank everyone who has taken the time to check their homes and hand in their firearms and ammunition.”
The firearms surrendered included functional and imitation models.
DI Bulmer added: “I am really pleased with the number of surrenders made. The two weeks gave people the opportunity to hand in their firearms without fear of prosecution for illegal possession.
“If you have any information regarding the use of weapons or suspicious activity in your area, please call 101 or Crimestoppers anonymously on 0800 555111.”
