The Smith & Wesson Model 300 hinged handcuffs provide significantly enhanced subject control compared to chain-style cuffs. The rigid hinged design restricts wrist movement more effectively, making them ideal for high-risk arrests, combative subjects, or transport situations where maximum security is critical. Law enforcement professionals prefer hinged cuffs when dealing with suspects who may attempt escape or resist arrest, as the limited range of motion reduces leverage and control opportunities for the restrained individual.

Yes, these handcuffs are Berry Compliant and Made in the USA (manufactured in Houlton, Maine). They meet federal procurement requirements under the Berry Amendment, making them eligible for purchase by federal agencies, military units, and government contractors. Each pair is stamped with a unique serial number and model number for authenticity and chain-of-custody documentation required in government procurement processes.

NIJ (National Institute of Justice) certification means these handcuffs have passed rigorous testing for workmanship, tensile strength, corrosion resistance, and tamper resistance according to NILEC and U.S. NIJ specifications. This third-party validation ensures the Model 300 can withstand real-world law enforcement conditions, including extreme force, environmental exposure, and attempted tampering. NIJ-tested restraints are the gold standard for police departments and correctional facilities.

The double lock feature on the Smith & Wesson Model 300 includes a slot on each cuff side that, when engaged, prevents the ratchet from over-tightening during struggle or movement. This protects both the officer and the subject from nerve damage, circulation loss, or soft tissue injury caused by cuffs tightening beyond safe limits. It also prevents suspects from deliberately tightening the cuffs to claim excessive force, providing liability protection for agencies.

The satin nickel finish on the Model 300 is specifically designed for corrosion resistance, making these handcuffs suitable for marine patrol, coastal agencies, and humid environments. The carbon steel construction with nickel plating resists saltwater exposure and moisture better than standard blued finishes. The non-reflective satin finish also reduces glare during tactical operations or nighttime arrests, providing operational advantages beyond durability.
