Very good information in this thread. For the most part it's the indian not the arrow. I've shot only one IDPA match where I saw someone use a 3rd gen S&W. It was a 3913. The shooter was classified as a master and he was shooting it with +p ammo. It was only a 4 stage indoor match, and he did quite well. Not sure why he wanted to shoot +p ammo given he told me he often carries a 22 mag.
