Methinks you have misconscrewed the intent of Bigslug post! The idea being that the 1911 is what it is, and often the dollars spent to tune it to a high degree of accuracy is not money well spent.
In my simple estimation a 1911 pistol is a companion pistol for the soldier, peace officer or brush popper, good for miscreants and anything with teeth and fangs that try to eat you. If can be pressed into service to add protein to the stew pot when needed. In it original configuration, it is a whale of allot of fun to shoot as well.
It got fixed up for target shooting back in the day when target shooting required the use of "The Service Pistol". Somewhere along the line, folks got the idea, that unless their 1911 wasn't turned up to high grade target/race gun accuracy, it just wan't good enough to own. This is utter and complete crapola.
Anyway, that is what I read into BigSlugs post. An unimproved "service grade" 45 Automatic (1911) is a wonderful friend in whom you can trust with your life and the life of those you love. Today these low end service grade 1911s come with much better sights and often a decent trigger pull out of the box. These are truly shinning times for Ol Slabsides.
