The "no sights thing" just reminds me of the recent story of the cop that fired something like 60 shots in a gunfight where he said "I didn't get a single hit until I remembered to use my sights and breath" ... And then he got something like 4-5 hits. But as I stated earlier, I am guilty of drawing, looking straight/linear down the barrel, and at least taking the first one/two shots while I'm "getting to the sights". Still hit the preferred area though!
I guess the point of so many replies to Randy's comment makes me think of this...
"I'd rather have regular sights than night sights on my carry gun" - No one Ever
I do buy into the "it's dark, I'm still waking up, can't see straight" thing... But again, as I've been taught... If you hear an intruder in your house you shouldn't go downstairs and look for them. You grab the gun, the fam, and huddle up in the safest place possible while you call the police.
And then another point that was driven home to me was... "Get a flashlight"
