I'm not bashing or whining about the internal lock,but another thread recently started about which revolvers don't currently have the lock made me think about why S&W never incorporated it into their autoloaders? If the mindset of the lock was to promote tampering by unauthorized users (children,thieves etc) then why were the autoloaders not equipped with them as well? It was not intended to be a "safety" so arguing that the autoloaders have safeties isn't valid. Just wondering aloud..
