Gun owners must have their forms signed by a professional person, official or someone of similar standing who has known them for two years - parish councillors are often chosen.
But now Brinsley Parish Council has told its members not to sign any more firearms applications and has urged other councils to follow its lead.
Councillor Tony Chettle said: 'We would, in effect, be saying these people are perfectly fit to have a shotgun when we sign the form for them. But we could be signing a permit for someone to commit a massacre like Dunblane.
Paul Clayden, director of the National Association of Local Councils, said: 'I believe this is a national first. If these councillors feel that strongly, then others could follow suit.'
