Is the barrel rifled so tightly to the chamber that the bullet impacts/engages the rifling upon slide lockup? If not, repeated chambering of a round usually moves the bullet outwards, thereby increasing the space within the cartridge. Sort of like an inertial bullet puller (fast motion/quick stop). The sudden stop on lockup is much more powerful than the initial movement of the slide starting forward, which is the motion which would cause bullet setback.

I agree with you.
While I have never used a Glock Model 22 (40S&W), I have used 1911's for over 20 years and have never experienced this problem. Even with some of the crappy cheap stuff I have purchased/been issued and used over the years.
Rimless rounds should head space on the shoulder or lip of the case. The bullet should not have any effect. Ideally, the bullet should just touch the rifling (which should be tapered at the chamber end of the barrel). This a manufacturing issue, all ammunition should be made to standard dimensions.
My guess is that there is a design flaw/material weakness in the glocks. Why Sig voids their warranty is troubling.

The Glock 22 is known for it's unsupported chamber.
That is, the cartridge case is not fully supported by the chamger, which increases the likelihood of these things happening.
The Glock 22 has a higher rate for this type of failure. When coupled with the large numbers of this handgun, especially in department armories, you see many more instances of the Glock KaBOOM.
That said, I've used a Glock 22 since 1993 with no issues and a factory barrel. If a user is worried, they can install an aftermarket barrel for $150.
