I haven't had the time to do a good Internet search on the specific issue, but as anecdotal evidence we need look no further than Glock Talk
When I joined in 2007 there were few .357sig owners posting comments, if I recall correctly. Since then the number of .357sig owners has greatly increased, with corresponding favorable opinions posted on various threads.
When I have time I will look into it, but I do believe I've recently read of the growing acceptance by LEO organizations of the .357sig and their adoption of this caliber as the issue pistol.
