The 586 Magnum is a sidearm featured in Tom Clancy's The Division, based on the Smith & Wesson Model 586 Magnum revolver.
Real World Version Edit
The Smith & Wesson Model 586, is a six- or seven-shot double-action revolver chambered for the .357 Magnum cartridge.
It is essentially the same weapon as the S&W Model 686, but the 586 has a blued steel construction, while the 686 has a stainless steel construction. Also, since the 586 was directed more to law enforcement, most have shorter barrels than the 686.
