I've seen some pretty well-bulged .45 Auto ammo. The worst would have been in +P loads, though I had some moderate bulging with hardball in a 1911 awhile back. It was a gun which had been accurized by the old-school method, with weld build-ups of the link lugs and extension filed and scraped to a hand fit. A longer link was then needed to match the taller lockup, but that caused the back of the chamber to overhang the feed ramp in counterbattery. So, the feed throat at the bottom of the chamber had to be moved even further forward than it had been originally, thus supporting the case even less. I don't know how Glock .45 Auto chambers compare.
