This 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 will not 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 manufacturers can still be held liable if a claimant can prove that the firearm had an actual manufacturing defect or did not operate according to the manufacturer's warranty.

Additionally, the bill states that the new limitations will apply to any actions filed on or after its effective date, and it will not affect claims that have already been adjudicated, settled, or dismissed prior to that date. The definitions of key terms related to firearms and their safety features are also provided within the bill. Overall, the legislation aims to provide greater protection for firearm manufacturers against certain types of liability claims while maintaining accountability for manufacturing defects.
