I just bought a Model 11 .223 with the accutrigger. This is my first savage and I am not familiar with the accutrigger so bear with me. Is the silver blade on the trigger suppose to act as a safety? The gun shouldn't fire unless you pull the silver blade with the trigger, right? Because while tinkering with it, I dry fired it without pulling the silver blade and it did still fire. I'm assuming this is not how it is suppose to operate...
