This model does come with the internal lock if that is what you are referring to. The model without the internal lock is 103061. Hope this helps!

The internal lock comes with the revolver though not specifically in the description. The lock prevents the trigger from being pull, the internal hammer does not mean it does not have the lock. S&W specifically makes a model that does not have the internal lock, noted below as model # 103061.
