The S&W Model 19 Combat Magnum is a K-frame revolver chambered in .357 Magnum, developed at the request of FBI agent Bill Jordan for a lighter, faster-handling magnum than the heavy N-frame Model 28. The 4.25-inch barrel is the classic configuration — light enough for all-day carry, powerful enough for serious duty. Type: Revolver Action: Double-Action Caliber: .357 Magnum Capacity: 6 Year introduced: 1957, USA Weight: 36 oz Overall length: 9.5" Status: Active Intended use: Duty, Service, Home Defense, Collector
