The Magnum Research Mk XIX Compensator System with 6" barrel is a serious handgun platform built for shooters who demand power and control. This single-action revolver chambers three of the most potent handgun cartridges available—.357 Remington Magnum, .44 Remington Magnum, and .50 Action Express—making it a versatile choice for hunting, long-range pistol competition, or serious backwoods defense. The compensator system is engineered to manage recoil and muzzle rise, helping you stay on target through heavy caliber loads and multiple shots.

Built on a proven platform, the Mk XIX combines a 6" barrel with adjustable sights for precision shooting at distance. The black oxide finish provides a durable, classic aesthetic while protecting against corrosion. At 71.4 ounces and 10.6 inches overall, it's a substantial handful—exactly what you want when you're handling magnum power. The black grips offer a secure, comfortable hold even when pushing these cartridges hard. Magazine capacity varies by caliber: 9 rounds in .357 Magnum, 8 in .44 Magnum, and 7 in .50 AE, giving you practical firepower for the job at hand.

This isn't a compromise gun. If you're hunting big game with a handgun, running steel at distance, or simply want a revolver that doesn't apologize for its caliber, the Mk XIX delivers. The compensator system is a genuine asset in a gun this powerful—it works, and it matters when you're cycling rapid shots or managing heavy recoil in less-than-ideal shooting positions.
