Trigger Pull: The Umarex Smith & Wesson 357 686 Revolver offers a trigger pull that is exceptionally light and smooth in both its single and double-action modes. The single-action mode features a notably shorter and slightly lighter pull with minimal take-up. In double-action mode, the pull becomes slightly heavier and lengthier, yet remains remarkably manageable for rapid and precise firing.

Accuracy: The Umarex S&W 686 pellet revolver stands out for its remarkable accuracy, delivering tight groupings as small as half an inch from 30 feet away in a semi-supported stance. Chronograph testing with RWS 7-grain lead pellets showed an average velocity of around 450 fps, surpassing Umarex's advertised 425 fps.

Build Quality: Crafted predominantly from metal, except for the rubber grips and detachable front sight, the Umarex Smith & Wesson 357 686 CO2 Pellet Revolver boasts a hefty feel, weighing nearly three pounds. As a high-end product from Umarex's German manufacturing line, its construction quality, fit, and finish are exceptional, with precise mechanical operations and excellent finish quality. Despite its premium price, this airgun is a worthwhile investment, likely to become a treasured heirloom.

Realism: This airgun is a faithful replica of the real Smith & Wesson 357 Magnum, closely mirroring its appearance and styling. Although it lacks a fully swing-out cylinder for simplicity and performance reasons, its design focuses on power and precision. The silver model could benefit from a color-matched magazine, which, being metal, could be customized. The Smith & Wesson official markings, substantial weight, concealed CO2 compartment, and recessed barrel contribute to its authentic appearance.

Do you feel lucky?

I feel very lucky purchasing this gun. It's accurate, powerful, and goddamn heavy. If you run out of pellets you can just hit them targets with it. All jokes aside , buy it. It's very well built, and you can't go wrong buying from ReplicaAirGuns. Thanks!
