I’ve seen videos, some people are VERY fast from condition 3.
But for me Travon Martin proved to me why I carry condition 1.
I depend on keeping my trigger covered with a good holster, keeping my booger hook off the bang switch, and the approximately 3 mile long trigger pull on my PF-9 to protect me from negligent discharges.
Springfield Armory XDs .45 here. Striker fired with trigger and backstrap safeties. Always ready to rock.
