See our Personalized Firearms policy summary for a comprehensive discussion of this issue.

Massachusetts law refers to “smart gun”-type technology in provisions relating to the sale of firearms without safety devices, but state law does not specifically mandate the use of such technology. Massachusetts law deems the sale of handguns and large capacity weapons without safety devices — including “smart gun” technology — an unfair or deceptive trade act or practice and declares such firearms defective.1 For further information, please see the Locking Devices section.
