Well, you could spell his name right, Charles Petter.
The Colt-Browning bushing serves two purposes, it centers the barrel in the front of the slide and it opens up a big hole so the barrel can be assembled from the front.
It does not "lockup" the action, that is done by lugs at the rear, linked or cammed into engagement.
Looking at my real deal Petter licensed SIG P210 and other bushingless pistols, I see wear marks on the barrel near the muzzle where it is tilted to bear solidly in the nose of the slide, aligning it at both ends. It is a lot like what I see on the barrel in the bushing of a tightly fitted 1911 type.
I think it was Charles Petty who praised the Walther P88 for that binding engagement. That pistol has a big oval hole, but the lockup angle brings the barrel to bear top and bottom.
BAC's target Smiths are different, there is a band around the muzzle forming a segment of a sphere that rocks in the bushing so it is freed until the slide brings it clear out of the bushing.
