The 125 grain .35ish cal bullets @ 1350+ seem to be excellent stoppers for sure. However, keep in mind the number of shootings that occur with 357 sig vs. 9mm, .40, or .45. What do you think the ratio of shootings would be comparing 9mm or .40 to 357 sig? I'm not sure there are a huge number of .45s in service but for .40 and 9mm there may be 20 shooting for every 357 sig shooting. Who knows? 20 to 1, 40 to 1, it's hard to say. If it were 20 to 1 you could expect twenty failures to stop for every one you would hear about with 357 sig. Just food for thought.
Remember also that other cartridges come in various bullet weights and power levels, low-recoil loads, ect. Some of which may not be a very good stopper. You can't hold it against the cartridges that have more variety, which may cause there to be some bad loads, while there could be some that work just as well or better than most in 357 sig. The 357 sig loads all have nearly the same external ballistic profile. It is a combination of caliber, mass , and velocity that works very well apparently as long as a proper bullet design is used.
