I prefer center hold as well. And when I had some sight work done on a number of my 1911s (in .45 ACP), I had the gunsmith, John Harrison, regulate the sights for POA = POI at 25 yards with standard pressure, 230 grain ammunition.
With that zero for self defense applications I can shoot point blank from contact to about 35 yards (with POI within an inch or two of POA for that entire distance).
"It is long been a principle of ours that one is no more armed because he has possession of a firearm than he is a musician because he owns a piano. There is no point in having a gun if you are not capable of using it skillfully." -- Jeff Cooper
