40SW refers to the .40 Smith & Wesson, a type of handgun cartridge developed by Smith & Wesson and introduced in 1990. It was designed to provide a balance between the higher stopping power of the .45 ACP and the higher magazine capacity of the 9mm. The .40 SW is commonly used in law enforcement and personal defense due to its effective performance and manageable recoil.
Out of the ones you've listed, .50 Action Express would be the most powerful, followed by the .45 ACP, followed by the 10mm, followed by the .40 Smith & Wesson.
The model 26 was in .45 acp, NOT .357. They were made from 1950 until 1966. So, to answer your question, there is no value in something that doesn't exist (a S&W 357 Model 26).
