The Gun Control Act of 1968 prohibiting the importation of inexpensive handguns prompted George Jennings to design the Raven MP-25, an inexpensive 7-shot, .25 ACP semi-automatic pistol. Jennings kept costs to a minimum by manufacturing the Raven from injection-molded Zamak, a zinc alloy. It came in chrome, satin nickel or black finish. The grips can be either wood or imitation mother-of-pearl handles. Raven has been referred to as the original "Ring of Fire" company. Along with Jennings Firearms (later Bryco Arms, now Jimenez Arms), Phoenix Arms, Lorcin Engineering Company, Davis Industries, and Sundance Industries, they were known for making similar cast zinc alloy Saturday night special type pistols.
