This interesting piece looks like a pen but transforms in seconds into a working legal pistol. Most "pen guns" fall into the legal category of "any other weapon,"
and as such, must be registered. R.J. Braverman’s Stinger Pen Pistols, however, must be folded into a gun-like shape before firing, earning them a Title I designation from the Bureau of Alcohol, Tobacco, Firearms, and Explosives (Title I firearms are just ordinary guns with no additional regulations imposed upon them).
These little pistols were produced in the early 1990’s and were chambered for .22 LR Rimfire, .22 Magnum Rimfire, .25 ACP, .32 ACP, and .380 ACP ammunition. They were just over 5 1/2 inches in length with a 2 inch barrel when folded.
While it is estimated that only around 4,000 R.J. Braverman Stinger Pen Pistols were manufactured, they are relatively easy to find today and usually for just a couple hundred dollars.
