The Enfield Revolver was a self-extracting British handgun designed and manufactured at the government-owned Royal Small Arms Factory in Enfield, initially in the .476 calibre.

The Royal Small Arms Factory (RSAF), also known by the metonym Enfield, was a UK government-owned rifle factory in Enfield, adjoining the Lee Navigation in the Lea Valley. Some parts were in Waltham Abbey. The factory produced British military rifles, muskets and swords from 1816. It closed in 1988, but some of its work was transferred to other sites.
