To modernize Federal firearms laws to account for advancements in technology and less-than-lethal weapons, and for other purposes.

This section would let the Act be referred to as the Law-Enforcement Innovate to De-Escalate Act of 2025.

This section would change how federal firearms law defines a firearm. It would insert the words or a less-than-lethal projectile device into an existing sentence in the definition of firearm in section 921(a)(3) of title 18, United States Code, so that a less-than-lethal projectile device, once it meets the new definition this section adds, would not count as a firearm under that law and would not be subject to the restrictions title 18 places on firearms. The section would add a new definition, paragraph (38), for less-than-lethal projectile device. To qualify, a device would have to meet all three of the following conditions. First, the device must not be designed or intended to expel, and must not be readily convertible to accept and discharge, either ammunition commonly used in handguns, rifles, or shotguns, or any other projectile at a velocity exceeding 500 feet per second. Second, the device must be designed and intended to be used in a way that is not likely to cause death or serious bodily injury. Third, the device must not accept, and must not be readily modifiable to accept, an ammunition feeding device that is loaded through the inside of a pistol grip or that is commonly used in semiautomatic firearms. The section also would require that if a person asks the Attorney General to determine whether a device meets this definition, the Attorney General must make that determination no later than 90 days after the date the Attorney General receives the device that was submitted with the request.
