I believe it was Col. Jeff Cooper who said the double-action auto-pistol was an answer to a non-question, or something like that.
A true double-action auto-pistol will be the same long pull for every shot. The double-action first shot followed by a single-action until you stop shooting and apply the safety [dropping the hammer] is a more difficult hand skill to learn than thumb the safety off, fire, thumb the safety on.
Good sights and a good trigger are the fundamentals of easy and good shooting. Good sight and trigger are often standard now on 1911s, easy to fix if you've an old gun.
