I own two Blackhawks in .41 Mag. I also own a Super Blackhawk in .44 Mag. I far and above perfer shooting the .41 myself. Noticeably less recoil for one thing. I also feel if you can't stop something with the .41, the .44 isn't probably going to do much better. It is true that ammo is more readily available for the .44, but you need to ask yourself just how much ammo are you really going to need? If you intend to shoot a lot, regardless of caliber, then reloading would be the best way to go regardless of choice. JMO......
