10" Contender. I've shot 1" groups at 100 yards with it. That's just a nice to have, though. I'm quite happy with 4" groups. However, it's the total package that matters. Handling, durability, sights, trigger, and other user features are just as important to me as accuracy. And it has to look good too.
Accuracy seems to be a code word for "I can't shoot but I want a gun that's inherently accurate to compensate for my lack of ability."
