940 CMR 16.04
Sale of Handguns Made From Inferior Materials
It shall be an unfair or deceptive practice for a handgun-purveyor to transfer or offer to
transfer to any customer located within the Commonwealth any make and model of handgun
that:
( 1) has a frame, barrel, cylinder, slide or breechblock:
(a) composed of any meta!having a melting point of less than 900°F,
(b) composed of any material having an ultimate tensile strength of!ess than 55,000 pounds
per square inch, or
(c)
composed of any powdered metal having a density of less than 7.5 grams per cubic
centimeter; or
(2) is prone to repeated firing based on a single pull of the trigger, prone to the explosion of the
handgun during firing with standard ammunition, or prone to accidental discharge.
(3) 940 CMR 16.04(1) shall not apply to any make and model of handgun which satisfies the
Make and Model Performance Requirements. The Attorney General may require that the
handgun-purveyor, or the entity testing the make and model in question on behalf of the
handgun-purveyor, provide a sworn certification verifying that the make and model met the
performance requirements. At the Attorney General's discretion, he may, upon 60 days notice,
require that any such test be performed again by an independent testing entity chosen by the
Attorney General, upon three test guns of the make and model purchased at retail. In such a case,
the prior certification shall be prospectively invalid at the conclusion of the notice period and the
make and model in question may henceforth only meet the Make and Model Performance
Requirements by obtaining a certification from the independent tester. A handgun-purveyor may
resubmit a make and model to the independent tester for testing an unlimited number of times.
