I have a S&W 57, 6" , factory nickel, with Skeeter Skelton's Deeson Bear Hug grips, made for my hand. I'm a big .41 Mag. fan, and use it in combo with my Marlin 1894S, .41 Mag. I bought the S&W in 1982.
I've used the revolver to kill a 400 pound Black bear, with one shot. He was in a tree, perhaps 20 yards up. At that time, I was using the Rem. factory 210 JHP cartridge. Because of the angle, the bullet hit his heart, clipped a lung and clipped the spine. I did not recover the bullet. I now use Joe Penny 220 gr hard cast and Beartooth Bullets 265 gr. hard cast gas check bullets.
When I'm out in the mountains, and especially in elk/deer camp, I wear it. I live in Black bear country and Mountain lion country.
I've killed one medium sized Mule deer with the Marlin .41 Mag., standing broadside at 90/95 yards. Went down like a ton of brick.
The .41 Mag. is a fine cartridge, in my opinion, and I wouldn't be without mine.
