Accidental Discharge: What I can learn from this.
I unloaded my 229, put new grips on it, dry fired it a few times, reloaded it and put it on the coffee table and watched TV for a while. Then I picked it up and dry fired it. Obviously I'd forgotten I'd reloaded. My bad. Fortunately nobody was home and the upstairs neighbors work at night. A round of Federal low recoil 135 grain went through three sheets of dry wall, the wood exterior wall of the house and through a drainpipe before it disappeared. The entrance holes were very well defined on all those surfaces and the exit holes were three times as big and uneven. I went outside and checked everything beyond that. it should have gone through the windshield of my car but it didn't. I checked the cars behind mine, the fence, the tree beyond the fence and the cars across the next street. No holes. I find it very disturbing that I had this AD, and am going to make sure it never happens again. Scary. I'm grateful no more damage was done and nobody was hurt. The house contains sound pretty well and no one called LE. Yikes. Now I'm off to the store for spackle.
