The 3-inch SP101 in .357 Magnum extends the barrel to improve velocity and add a front sight for better aimed fire, while remaining shorter than a service-length revolver. Popular as a woods carry gun and backup for hunters. The 3-inch barrel extracts meaningfully more velocity from .357 loads than the 2.25-inch without becoming unwieldy. Type: Revolver Action: Double-Action / Single-Action Caliber: .357 Mag Capacity: 5 Year introduced: 1988, USA Weight: 27 oz Overall length: 8" Status: Active Intended use: Woods Carry, Self-Defense, Hunting
