I had a 629 with 8 3/8" barrel and it was great. Managed to get a 2-3" group at 100 yds with iron sites, once. Could never repeat it. It was ok with shoulder holster but not much fun to carry while hunting, tried that a couple times.
Don't know much about the Redhawk but have always liked what I read about it. I shot a .44Mag Super Blackhawk and that was fun and pretty accurate.
Heck, I would be comfortable with either Ruger or S&W. I am sure the forgein made .44's are good but I prefer to see made in the USA, except for my Sako.
