Robert J. Braverman
The inventor and his company.
Meet the inventorHistory
A dated record of the design, its patents and the three companies that made it until 2004, followed by the re-engineered Stinger today, with the source for every entry.

Part one: production
Robert J. Braverman designs a single-shot pistol shaped like a pen.
The application for US 5,062,230, “Pen gun”, a straight design, is filed.
The application for US 5,062,231, “Duel profile pen gun”, is filed: carried as a pen, fired only when folded.
Both patents are issued to Robert J. Braverman of Marblehead and Isaak M. Shklyarov of Boston, and assigned to R. J. Braverman Corp. of Winthrop, Massachusetts.
Federal regulators treat the design as an ordinary handgun rather than an “Any Other Weapon”, because it cannot fire in its pen form. ABC News later dated the classification to June 1990; other accounts place it in 1991.
American Derringer Corp. of Waco, Texas, markets the design as the Model 2 “Pen” Pistol.
R. J. Braverman Corp. sells the design as the Stinger from Meredith, New Hampshire. Remcon North Corp. makes the guns, which are marked with the Meredith address.
Soldier of Fortune puts the Stinger on its cover (“Pocket Stinger: The Pen Gun Is Back!”) and reviews the Stinger Pen Pistol from R. J. Braverman Corp. The 1995 feature
Production of the first Stinger ends. Wikipedia gives 1996; The Firearm Blog’s reviewer dates it to 1997.
Stinger Manufacturing Corp. of Sault Ste. Marie, Michigan, revives the design as the .22 “Pengun”, initially with the help of Bob Braverman. ABC News describes Marc Lefebvre as a major investor in the company.
Robert Braverman applies for a patent on an improved “dual profile pen gun” (application 10/292,108). The 2004 published application
ABC News reports on the Pengun, and the Violence Policy Center asks regulators to reclassify it. An ATF spokesman tells ABC News that the folding design is classified as an ordinary handgun because it has to be reconfigured to fire.
Stinger Manufacturing stops production. The Firearm Blog, reporting the founder’s view, attributes the closure to politics rather than sales.
The 2002 application is published as US 2004/0088897 A1. It is later abandoned; no patent is issued on it. Its front page and drawing sheets
