In my searches I have run across guns without safety switches. Being that I am a newbie, I am not sure if I should even consider buying a gun with no safety. But on the other hand, some say it is just handicap when trying to defend yourself under stress. Still others say that to have a gun with no safety is to be negligent and endangering to yourself and others. I know that a safety is not to be 100% reliable since it is a mechanical stop and could fail. Thoughts anyone?
