Snubbies are plenty accurate. I can hit a 6" plate at 25 yards probably 90% of the time with my S&W 442. It all depends on a proper and consistent trigger pull. Now, shooting five shots in five seconds I can't shoot that well. I have a lot more practicing to do.
This pic is from when I first got the gun and was still a pretty inexperienced shooter. Distance was about 10 yards and group was probably around 1.1". I later painted the front sight ramp with a base coat of white paint and then a bright red/orange color using toothpicks and model car paint. Now I can align the front sight in the rear sight and put it on target much easier.
