I have a .32 Smith and Wesson that I got a long time ago, and it has the Saf T Lok on it. Since the lock is right on it I don't store it in my safe, and I keep it handy in a drawer (plus, I always thought the lock with the levers was pretty cool.)
However, I just did a search here, and the feedback towards the lock was very negative. Is it not safe? It has always opened up quickly and easily for me, but is it capable of making the revolver misfire? I keep it loaded, as it was sold as a safe way to keep a gun loaded, locked, and easily available.
