Raven Arms MP-25

Raven Arms was a firearms manufacturer established in 1970 by firearms designer George Jennings. The Gun Control Act of 1968 prohibiting the importation of inexpensive handguns prompted Jennings to design the MP-25, a .25-caliber semi-automatic pistol, and enter the firearms business. Raven has been referred to as the original "Ring of Fire" company, a term describing companies known for producing inexpensive Saturday night special handguns.
Raven kept manufacturing costs to a minimum by building their guns from injection-molded zamak, a zinc alloy.
