You might very well be right. I had a model 57 which was not only beautifully made, it shot as well as any revolver I have ever owned. It pretty much equals the .44 mag and has thicker cylinder walls and should hold up a little better.
Despite that, I do really like the model 29 and the Super Blackhawk. Also ammo is much more available for the .44 mag.
If you don’t handload the .44 is clearly a better choice, but the .41 is a handloaders dream.
