It's stories like this that make me shy away from pocket autos and stay wit the old fashioned J frame snubs. Seems that the smaller the gun, the more succeptible it is to a screw up regardless of who makes it...
One thing that wasn't mentioned is that a lot depends on the shooter - how he grips the gun and how uniform his grip is from shot to shot. These things are harder to master on a small gun than one that gives the hand a little room, but that can't be considered a defect of the firearm. It's the price one pays for the "micro" design. That said, if it absolutely, positively has to go bang, a Chief's Special won't take a back-seat to any of the small autos.
