BlackRock, calling the issue of gun manufacture and sales one of “tremendous urgency,” is engaging with its portfolio companies:

It said it has already had “constructive discussions” with some of the companies. It plans to ask gun makers how they’ll deal with the reputation and legal risks associated with manufacturing civilian firearms, and if they monitor whether their products are used in crimes.BlackRock will ask retailers what proportion of their sales firearms and ammunition represent, and what steps they have taken to prevent the misuse of firearms that they sell.
