The flat on the barrel feet is what controls the dwell time, and it's very important for accuracy, because it keeps the barrel on the same plane as the bullet goes down the barrel.
Bulleyes gunsmiths fit the barrels this way, but I read somewhere (don't remember) that guns built for combat shooting, they want them only lock up at the very end with very short dwell time.
