I thought we were staying on topic....
But to answer your question directly - I have Redhawks in both 44 Magnum and 45 Colt. I would carry either one in grizz country. When loaded to their potential, they are very close ballistically.
For factory ammo, look at Buffalo Bore.
Their 325 grain hardcast load in 45 Colt does 1269 fps out of my 4 inch Redhawk. This is what I carry although my own reloads are pretty close in performance.
Their 340 grain hardcast load in 44 Magnum is supposed to do 1401 fps out of a 5.5 inch Redhawk. I haven't chrono'd this load because I like my own reloads.
What you want is a hardcast bullet with a wide meplat that weighs at least 300 grains doing at least 1200 fps. That BB 325 grain 45LC load is pretty much the sweet spot for a hiking gun in grizz country.
If you don't reload, then forget about 45LC and get a 44 Mag.
Of course, all of this depends on having the proper gun.
