I did some searching and couldn't find this addressed. I realize some of it may be controversial ala "safe an AR during reload or not", but would love input from some of our resident shotgun experts. @TCinVA, @jlw, @Tom Givens, I'm sure I'm probably missing a few.
In the scenario in which you are searching with a shotgun, clearing a house let's say, do you have the shotgun on safe, finger/thumb on the safety, or are you off-safe with finger in register position? I figure trigger finger is in register position regardless. I can see with a Mossberg's thumb-activated safety where it might make sense to leave it safed as you can de-activate the safety while simultaneously moving your finger to the trigger, but with pretty much everything else (Benelli, Beretta, Remington) you're going to slow your response to the need to shoot by first de-activating the safety.
Bottom line question: do you believe it to be unsafe or irresponsible to search with an off-safe shotgun provided we have proper trigger finger discipline?
