The bill introduces a new section, RSA 507-D:6, which limits the liability of firearm manufacturers in product liability actions specifically concerning certain design features. Under this new provision, manufacturers cannot be held liable for claims related to the absence or presence of features such as a magazine disconnect mechanism, loaded chamber indicator, authorized user recognition technology, or an external mechanical safety. However, the bill clarifies that this limitation does not apply in cases where a claimant can prove that the firearm has a manufacturing defect or does not operate according to the manufacturer's warranty. Additionally, the bill maintains that other defenses available to manufacturers under existing laws remain unaffected.

The bill also includes a severability clause, ensuring that if any part of this section is deemed invalid, the remaining provisions will still be enforceable. The new liability limitations will apply to any actions filed on or after the effective date of the bill, which will take effect upon its passage. The fiscal note indicates that while the bill may impact the judicial and correctional systems, the exact financial implications for state and local governments remain indeterminable.
