Here's the story...
I always keep my guns loaded with a full magazine and an empty chamber while they are in the house. May not be the best tactically but anyway....
Last night I was taking pictures of my Sig 229 .357 to place along with my classified ad here at the forums. I took pictures of the left side the right side, and figured for the pictures sake I would put a magazine in the gun, and one in the magazine holster. MISTAKE: I put a loaded magazine in the gun. I know, not a good idea. In the process of taking the pictures, I decided to take a few with the action locked back. Immediately after those couple of pictures I went to put the gun up. In my inspection of the barrel, ( i always check the barrel before i close the action ) i saw no bullet chambered, and somehow missed the loaded magazine staring me in the face through the ejection port. As a second safety check, I always dry fire into something safe, most often the ground, in this case the mattress. When I pull the trigger for a dry fire, I assume a round is going to fire, however in the past 6 years of gun ownership, nothing ever has. *BOOM*,.... I just blew a hole in my mattress at point blank range, through the mattress, box spring, carpet, and a bit into the concrete. Scared the heck out of me, however if I hadn't have been safe in the way I handled the firearm, ( even though it went off ) something much worse could have happened.
Take my mistake as a lesson, don't ever become lackadaisical when practicing proper safety when handling firearms. Because I followed Rule #1, i lost a portion of my mattress instead of something else.
