Here's the main point: ALL guns are incredibly dangerous and safety must be given top priority. "Out of sight, out of mind" seems to be fairly common with hunters. All guns have hammers--exposed or hidden--that need little urging to do their job. With an exposed hammer gun the risk of a misadventure is constantly being impressed on the shooter. I mean, those huge hammers stretching over the firing pins is a constant reminder that the utmost attention need be given. With a "hammerless" gun that threat is concealed and easily ignored or delayed. I think if really reviewed honestly most of us shooting hammerless guns have at one time or another forgotten that we had slid the safety off and forgotten it for a time. Nothing could be more dangerous. Hammer guns do not allow this slip to pass without notice.
