I have seen one have catastrophic failure on one occasion. The magazine shot out the bottom and the hand grip split doen the right side and pinched the offciers hand. It was a personally owned pistol and they were shooting ultrmax remanufactured ammo.
The shooter had no serious injury though his hand was sore where the grip expanded and then closed on the skin of his hand and i'm sure it stubg a bit.
It was faulty ammo. I have not seen one fail in similar manner (catastophic) in the nearly 2000 we have issued in the past 10 years.
