I read a report years ago from Henrico County, VA Sheriffs that basically said that they were evaluating it because of its similiarity to 357 magnum 125gr.
Their evaluation was that while it did not duplicate the loading exactly ballistically, the end results were the same and the guns were lighter, less recoil, and higher capacity.
The biggest highlight of the review was that the 357Sig/125 loading performed the best when confronted with car windshields as an intermediate barrier. For trivia 40/155 did second best. Wish I could remember what ammo they were using...
They adopted it.
