I commented in the gun section, but will say it again. Glad you are ok. And I don't carry my ML with a cap in it. If I am stalking with it I do not sling the rifle. With proper gun handling you don't need a safety and certianly should not trust them.
The only time I actually carry a loaded weapon is when I am bunny or bird hunting. And the the gun is at the ready position all the time. If I sling it to walk to a new area I unload the chamber and put the shell back in the tube. It only takes me a second to rack a round into it if I have to. This doesn't works so well with a ML though.
And like I said in the other post, do not touch the trigger unless you are ready to shoot something. I know this is not what happened to you though. Just saying it again.
