357 mag isn't just more versatile than the other calibers listed, it is the MOST versatile caliber of all guns. Revolver or semi-auto. With it's ability to shoot 38spl or 357 magnum, you can get loads as light as a 380acp. Into the normal 38spl. Into the 38spl+P which will get you into the lower end range of the 9mm. To the normal 357 magnums that will take you beyond the 9mm and 40sw and 45acp. Into the heavy 357 mag and +P that will take you beyond the 40sw,10mm, etc... Even to the light side of the 41 magnum. (Such as buffalo-bore 357 mag+p at 180 grain, 1400 fps, and almost 800 ft/lbs.
Then, throw in the fact that you can buy a snub nose 38spl+p backup pistol. Or even a winchester, rossi, etc... lever action in 38sp/357 magnum. Makes a great deer rifle out to about 100 yards with the right load.
The 41 mag is definitely a pretty powerful round. But that's it. What you see is what you get. There is no variation. With the 357 magnum, the only thing that's potentially LIGHTER is a 32acp and below, and the only think HEAVIER is a 44magnum and above. The 357mag has a load in some ammo, that can equal just about every possible load in between. The main reason the 357 mag hasn't remained as popular as it once was, is because hollywood and some people have made you believe that you need 10-20 rounds in a magazine, and that you need to change them out quickly. And a semi-auto in 357 magnum isn't very practical. (E.g. Desert Eagle). Get the 357 magnum.
