The majority of my doublegun shooting with hammers has been with a percussion muzzle loader. For breech loaders I prefer hammerless. This gun has safety & full cock notches, no half cock. In the field I always carried it with hammers in the safety notch. I have small hands & short thumb no way I could safely cock both hammers together. Upon flushing game i cocked one hammer & fired. If there was time or need I cocked the other & fired again. Sure I lost some shots but that was far preferable than endangering a hunting companion or dogs.

Never, Ever carry a gun muzzle or breech loading, hammer or hammerless having non rebounding locks with the hammer down resting on a live cap or primer, that is a total No-No.
