The .357 Sig is a great round...The 125grn pill is pushing just about the same speed,as teh 125 out of the .357mag. Both are hp rounds,and the mag beats it by about 50-75fps...Thats fairly close,in a handgun used for personal protection agains the evil types. The hands down winner that i have ever seen is that 125jhp in a .357 mag for ending a personal encounter...Its running about 90 percent with that round. I think you could do a lot worse in picking a personal defense round other that the .357 Sig. Now i know someone is going to argue with me,but from personal observations,it is the best for what you want to use it for. I also carry a 10mm,and it is no secret that I like it a lot,but..i have some old NORMA rounds with which it is fed for self defense purposes....good luck...king
