Remington's Golden Saber Bonded line of ammunition is a law-enforcement-only product, meaning it is not sold directly to civilians. Spend some time on the Internet, however, and you'll turn up various sources where it can be procured. Remington bonded the jacket and core of the Golden Saber together to help the bullet retain its expanded shape and weight after penetrating various barriers to which the ammunition is exposed during FBI testing protocol.
This is really the only advantage the Bonded version offers over standard Golden Saber bullets. The standard-velocity 9 mm 124-grain Golden Saber Bonded bullet expanded 1.6 times its original diameter in 10 percent ordnance gelatin and penetrated—on average—an almost optimum 11.5 inches.
