Why use a thick flange over a conventional bushing?

Bushings are key players in the role of accuracy for the 1911. A loose sloppy bushing will decrease accuracy and provide extra wear and tear on the bushing itself. The thick flange provides a larger and stronger surface area for the barrel to rest on throughout the firing cycle of the gun. It also adds strength to the front part of the bushing which has a great deal of force exerted on it in its role of holding the spring plug in the gun.
