I am fan of a hammerless revolver for certain applications but a S&W j-frame sized gun with a 2 inch barrel is not going to give you the accuracy you are looking for.
A Ruger Service Six in stainless has been my go to for almost 30 years if I'm going to open carry in the woods or on a farm. It is a 4" barrel .357. It is simple, powerful, and reliable. Accurate enough, especially firing single action. Heavy but the grip size and overall weight are welcome if you're firing full 357 loads. I usually carry it cross draw on my left hip so it is accessible when seated in a vehicle.
If weight and concealability are bigger concerns, then I would go with the S&W Shield in either 9mm or 45. I think the 40 would be punishing. If you can stand the bigger size, then the M&P 2.0 compact would be a good choice also. All are available with a safety.
