Owners of the Charter Arms Double Dog find the dual-caliber configuration genuinely useful. The ability to run 9mm through the same revolver as .357 Magnum gives flexibility at the range, and 9mm costs less to practice with.

The ported barrel is a point of discussion. Some shooters appreciate the reduced muzzle flip when shooting full-power .357 Magnum loads, while others note the ports add noise and muzzle blast, especially in low-light conditions. The walnut grips are considered attractive but can feel thin under heavy recoil.

Build quality opinions are mixed. Charter Arms revolvers occupy a budget-friendly tier, and the Double Dog reflects that. Most owners report reliable function out of the box, but a portion note the finish and fit are not on par with higher-priced revolvers. Value for the price is the main draw.
