This Devel Corporation pin or tie tack is a scarce piece of late 20th century firearms industry memorabilia tied to one of the most innovative custom pistol shops of the concealed carry era. The pin features a red enamel face with stylized "DEVEL" lettering, mounted on a brass backing with clutch-style fastener. It is housed in a small round plastic display case, adding a layer of protection and presentation.

Founded in 1979 by Charles Kelsey in Gates Mills, Ohio, Devel Corporation became widely respected for its advanced custom work on service pistols during a formative period in modern defensive handgun development. The company specialized in "full house" modifications to platforms such as the Smith & Wesson Model 39 and 59 series, Browning Hi-Power, and the M1911, producing compact, high-capacity pistols with shortened slides, improved ergonomics, and enhanced reliability. Devel's work directly influenced the evolution of modern concealed carry handguns, particularly in the refinement of compact fighting pistols for professional users.

The pin remains in very good condition, showing little to no handling marks. The enamel retains strong color and clarity, with no significant marks observed. The reverse hardware is intact and functional, and the included display case shows minor wear. As a collectible, this piece represents a tangible connection to a highly influential custom shop and an important era in the development of modern defensive firearms.
