Checked out S&W website and see where they offer the Model 629 classic in 5 inch, 6.5 inch, and 8&3/8 inch barrels. I guess if you want to hunt with this revolver then the longest barrel is the way to go? Also, what factory ammo do you recommend for Eastern whitetails? What is a reasonable maximum range that you can humanely take deer with this revolver and load? Lastly, does anyone hunt with iron sights, or do you only recommend a scope?
