There is one the Smith&Wesson Model 329 PD. It weighs 25.1 ounces (empty) or at least what I consider light weight compared to the other 44 mags weighing 40 ounces or more (empty). I have heard that if you switch the woods grips out to some type of rubber grip the recoil is no where as bad. Still a good amount but not as painful.
But also look at it like this how many rounds do you think you will be able to get off and put those rounds on target while a bear is charging at you? Noting this bear is bounding with his heading bobbing around and a bear can cover 50 yards in as little as 3 seconds. Will you even be able to draw the weapon an at least get a round off? Me I couldn't do it unless I practice a lot. Also that adrenaline will be running so you will likely not notice the recoil just like how a lot of us never notice the recoil when we shoot an animal or at least I don't but I sure as heck notice it at the range.
