40 years of hunting, shooting and gun handling many 10s of thousands of rounds has never produced a ND. I have rarely ever used a safety on a gun.
To me a safety gives people a false sense of security.
I agree with this. Any mechnial device will wear out. The main safety is between the user's ears. This why I tell people who are wanting to get into guns is to get a revovler. They are a bit more forgiving then say a 1911 or a GLOCK.
