I have a S&W 629 Magna Classic 7.5" 44mag, and 2 Super Blackhawk Bisley SA 44mag (one blued and one stainless hunter).
I think these are more comfortable to shoot as opposed to the Redhawk although the Redhawk is a hell of a sturdy gun. My wife has the Redhawk and does pretty well with it. The grip didn't fit my hand well and I think that is the main contributing factor as to why I prefer the S&W and the Bisleys. I have shot cases of factory 44mag ammo thru all of them (Magtech, Federal, Remington) and haven't had any issues.
