In light of perfect terminal ballistic execution in arms gelatin amid lab testing in the late 1980s and mid-1990s, the .40 S&W earned status as “the perfect cartridge for individual resistance and defense purposes.” Aside from the flawed relationship between weapons gelatin ballistics and genuine ceasing power, faultfinders indicated the diminished force of the round contrasted and the 10mm Auto it depended on. Ballistically the .40 S&W is practically indistinguishable to the .38-40 Winchester presented in 1874, as they have a similar slug width and projectile weight, and have comparative gag speeds. The vitality of the .40 S&W surpasses standard-weight .45 ACP loadings, creating between 350 foot-pound and 500 foot-pounds of vitality, contingent upon slug weight.
