I bought a plain-Jane "Sportsmans" safe outta 'Shotgun News' 20 years ago and it came with a conventional S&G dial lock. It proved to be so finicky and laborious (to say nothing of the fact that I could barely see the little tick marks on the dial) that I finally paid a locksmith to install an electronic lock. It was the right decision as, aside from periodically replacing the 9-volt battery, the replacement electronic lock has been completely trouble free for many years. I still have the original S&G lock if anyone's interested.
