The United States Undetectable Firearms Act of 1988 (18 U.S.C. § 922(p)) makes it illegal to manufacture, import, sell, ship, deliver, possess, transfer, or receive any firearm that is not as detectable by walk-through metal detection as a security exemplar containing 3.7 oz (105 g) of steel, or any firearm with major components that do not generate an accurate image before standard airport imaging technology.^[1]

It was signed into law by President Ronald Reagan on November 10, 1988.^[2]

Overview

The general effect of this legislation is a ban on the manufacture, possession and transfer of firearms with less than 3.7 oz (105 g) of metal content. The bill also requires handguns to be in the traditional shape of a handgun. The Act excepts from its prohibitions the federal government and its agencies, and may offer a safe harbor for licensed manufactures testing to determine if their firearms meet the Act's criteria.

History

What became the Undetectable Firearms Act began as an attempt to ban handguns like the Glock 17 in the mid-1980s.^[3] Pistols like the Glock had frames and grips made from lightweight polymer, and their novelty prompted public criticism that their relative lack of metal content meant they might be able to slip past airport metal detection and be suitable for use by terrorists.^[3][4][5]

Initial proposals to ban handguns with less than 8 oz of steel were opposed by the National Rifle Association of America (NRA), and what resulted was a compromise that banned guns with less than half the metal content of the Glock.^[6][7] The NRA agreed not to oppose the Act because it did not affect any existing guns. Introduced by William J. Hughes (D-NJ), it passed overwhelmingly in October 1988.^[7]

The gun control lobby was eager to promote it as one of the first successes of groups like Handgun Control, Inc (later the Brady Campaign).^[7] The Act set the stage for the 1994 Assault Weapons Ban.^[7]

Renewals

The original Act had a ten-year sunset clause, and would have expired on November 10, 1998. Congress subsequently renewed it in 1998 for five years,^[8][9] in 2003 for ten years,^[10][11] in 2013 for another ten years,^[12][13] and in 2024 until March 8, 2031.^[14]

Proposals to extend the scope of the law at the 2013 renewal were unsuccessful. At that time, the NRA continued to support the law but opposed any extension of its scope.^[15]

Application to 3D printing

With the advent of projects like the Wiki Weapon, 3D printing technologies have been noted for their abilities to help create largely polymer and ceramic firearms.^[16][17] Various groups of makers and tech enthusiasts have experimented with the technology in this capacity as well, leading to widespread speculation that traditional methods of gun control will become increasingly inoperable.^[18]

Proposed renewals and expansions of the current Undetectable Firearms Act include provisions to criminalize individual production of firearm receivers and magazines that is not detectable by a walk-through metal detector, measures outside the scope of the original UFA^{[citation needed]} and not extended to cover commercial manufacture.^{[19][20][non-primary source needed]} The modernization proposals have been criticized as disingenuous attempts to suppress adoption of and experimentation with 3D printers in home gunsmithing.^{[21][better source needed]}
