I have both 44 and 45 in 4-5/8” , RedHawks , the 44 mag will almost drop me with the magnum crack, just like a 357 does. I can shoot my 45 with hotter than cowboy loads, doesn’t bother me at all, that’s why I carry my 45 revolver if I don’t carry my auto’s , I carry on Ranch every day in chest holster’s and I never can put in ear plugs when something runs out, save your ears and get 45 .
