Yes the tang safety! I forgot about it since all of my shotguns have one, even my pump shotguns. It shouldn't take long to get accustomed to flicking it off during gun mount since it is the most natural and accomodating safety there is.

For the first time ever with either a rifle or shotgun, I notice my trigger finger whacking the front trigger when under recoil from using the back trigger on my DR a couple of weeks ago. Our various bird seasons had just ended and I started shooting my DR in prep for a Sept safari. When shooting birds I grip the gun rather lightly with my trigger hand. Gripping my rifle a bit tighter cured the problem.
