Smith & Wesson Warranty Statement

The federal Magnuson-Moss Act (the "Act") does not require any business to provide a written warranty. The Act allows businesses to determine whether to warrant their products in writing. However, once a business decides to offer a written warranty on a consumer product, it must comply with the Act. Rather than trying to comply with the various provisions of the Act, Smith & Wesson Corp. has simply decided not to provide any written warranty for the products offered for sale on this website (excluding Smith & Wesson restraint (handcuff) products, which have a Limited Warranty). You may have other rights, such as implied warranties, that vary from state to state.

It is our intent that the customer be completely satisfied with the products on this website. Please contact our customer service department with any questions or concerns you may have regarding the products on this website. All liability is excluded in the event that applicable product warnings and instructions are not observed. Smith & Wesson Corp. reserves the right to make changes at any time and without notice, in prices, to change specifications or designs, to add or remove accessory materials, and to add or delete items without incurring any obligation.
