The money will be distributed through the Home Office's Connected fund, which has so far given £1.25m to 300 small voluntary groups working on gun crime and related issues. A significant amount is likely to go to projects based in south London, after a spate of fatal shootings there.
Last week chief executives body Acevo called for a 'third sector action zone' in south London to combat gun crime. It wants national charities to work with community groups to build social cohesion and fight exclusion.
Chief executive Stephen Bubb said: "Third sector organisations can lead social regeneration in the area, just as many have done with economic regeneration elsewhere."
