Thing I don't like about S&W9mm's, is that they aren't safe guns at all, my grandpa has one, and it's safety is the hammer, mainly, but when you chamber with the slide, the hammer is automatically cocked, and if you pull the trigger, it'll go off, it really isn't a safe gun,
You'd better read the owner's manual or have someone show you how the pistol works before you hurt yourself or someone else- its pretty obvious that you don't understand how the pistol works.
