History
Developed by Wildey Moore in the late 1970s alongside the Wildey pistol, the .475 Wildey Magnum was designed to bring rifle-level power to a semi-automatic handgun platform. The cartridge gained pop culture notoriety from the 1984 film Death Wish 3. Production has been intermittent due to limited demand and the niche nature of the platform.
