This is a remarkable story. Via cw56.com in Massachusetts:
Digging through the snow with his paw, the German Shepherd not only located the gun, he fired it. It was a loaded Ruger semi-automatic.
One remarkable aspect of the story is that the reporter obtained and reported the make of the gun and that it was a semi-automatic. Maybe with all the clamor for gun control they are learning a little bit more about the mechanics.
I promise not to keep beating this dead horse, but if only the Ruger had a manual safety, or even a grip safety, that discharge likely wouldn't have happened.
