The most accurate and smoothest S&W I own is a 15-4. Awesome gun! However, I do have an itch for a heavy barrel model 10. Never cared too much for the looks of the pencil barrel 10's, but after handling a few, I can see its one I'll eventually own. They feel light and quick, and it seems a little easier/faster to pick up the front sight. Liking them more and more. Lol
