This 40 S&W cartridge features a 125 grain frangible bullet. Unlike the tried and true FMJ that shooters usually employ at the range, the frangible bullet contains no solid metal. Well, its copper and tin are in fact solid in the chemistry teacher’s sense of the word, but because the powderized metals in this bullet have been hardened together through heat and pressure they pose virtually no risk of creating dangerous splash-back or ricochets. The frangible bullet hits a hard surface and disintegrates.
