Marshall and Sanow wrote a book on the subject of one shot stops among other things. The 125 grn .357 mag had the highest rating / score. The 185 grn +P a close second in .45 acp.
The .357 is usaully used in a revolver, the .45 acp usaully in an automatic. You can decide for yourself what platform you prefer, they both have advantages and disadvantages of coures.
They both work. How good are YOU?
I used to depend on the .45 auto but now I am disabled and depend on a Colt Detective in .38 spcl. I think it'll suffice. :-)
