There are good reasons to use an AR for HD. The type of bullets available for HD was a major factor in me buying an AR in the first place. That said yes it's a good idea to lean to point shoot effectively. And the really good thing about an AR for HD is the amount of ammo you have ready to go. Also I have had lights mounted on my previous HD firearms, 2 shotguns, And I've recently gone back to a shotgun for my primary HD weapon. That is pending testing. I don't want to count on a shotgun only to find the one I picked is a lemon.
