Well, let's see..... At the moment of firing, what connects the barrel and slide? At the front end, the barrel bushing. At the rear, the barrel is locked to the slide by the matching grooves on top of the barrel, and underside of the slide. Purpose of the link is to pull DOWN the rear end of barrel after recoil starts. Unless I totally misunderstand the cycle of a 1911A1, I just don't see it.
