Working in the firearms industry as long as I have, I have been asked this question many times.
Just a bit of history first...hunting is generally a rifle game. It has been since rifles were invented. Why? Couple reasons, first and foremost they are/where more accurate than pistols. Secondly, most of in all people can shoot a rifle more accurately than a pistol. Secondly the pistol didn't have the power of a rifle. Why is that? Well a rifle is more stable, because of better support. Power, well case capacity, yada yada, We all know this stuff. This is not Rifle vs Pistol thing. But I needed to set the stage...
How many double action rifles do you know of???

Now knowing a rifle is primarily a hunting firearm, IF DA was better, there would be DA rifles and shotguns, not just handguns.
Strictly from a hunting stand point, the SA is better, because it affords a more accurate shot.
From a defensive standpoint, I can see the argument in favor of the DA.
Again I'm a pistol guy but the pistol doesn't cut the mustard for defensive use when large animals are the issue. Sure I'll still carry one, but if I feel the need for defense from a large toothy critter a 12Ga pump is my companion.
I have three hunting hand guns. Two are SA revolvers the third is a Single Shot (Still a SA

).
JMHO,
