Remarkable! I couldn’t hit squat when I had to fire that vest pocket bazooka in the military.
There are a few really accurate .45acp tools now available. One, Rock Island Armory, is producing a flared barrel model which doesn’t use the barrel bushing and locks up when the slide seats. Good tools ...
Most of the .45 colts used in training in the service are shot out junk with barrels as smooth as a water pipe and bushings as tight as your underwear after you have lost 40 pounds.
It's not the fault of the weapon's design it is the quartermaster who doesn't bother to replace worn out equipment.
