This is a newer Shield in .40 S&W. Female was shooting it and apparently didn't notice the reduced recoil and sound of what was more likely than not a squib round.... pulled the trigger again and it blew up on her.
Face and hand injuries for her. Coworker took these three photos, unfortunately not more. He said the pistol owner is a "gun guy" and is definitely contacting S&W so they can examine it.
Ammo was some "good" Winchester hollowpoints. I'll try to find out the exact type.
