Nice wheel-gun scary, these are ideal for concealed carry. Light weight, small and plenty power in the Special cartridge. Iirc the barrel is, as Phosphorus says, just under 2 inches.
I never carried one Mike but several officers I worked with did, most of them used a pancake type holster worn on the back side of the hip. During cold weather they simply carried it in a jacket pocket, snagging the hammer was not an issue with them as the idea was to simply fire it from the pocket in an emergency! There is no time for wild west theatrics in a gun fight when seconds count and lives are on the line. I have heard of misfire issues when going to a "bobbed" hammer, something to consider. The springs do not compensate for the loss in hammer weight is the way it was explained to me.
They are surprisingly accurate for so short a barrel but of course it's primarily for close work. As with any handgun there is a blinding fireball at night. Practice closing your firing-side eye the instant before pulling the trigger at night to prevent the bright spot in your vision. Learn to fire and strike your target in a critical area out to about 20 feet without the sights. With practice this can be done easily if you are consistent in how you hold the pistol, "instinctive shooting" is surprisingly accurate and saves you critical time. Practice...practice...practice!
Nice revolver,
I think you are going to enjoy this one!
