1st, remember that Glock has different cut rifling and clearly state to owners not to use reloaded ammo. The consensus, however, is that as long as you just reload jacketed bullets, you’ll be OK.

All manufacturers say this. It's for liability only.

Glock specifies to not use cast lead bullets with their polygonal rifling.
It is not that big of a deal.
Glock leaves a bit of the ammo casing unsupported in the chamber because glock wallows out the feed ramp a bit to aid feeding.
If worse comes to worse the case can blow out but it is not catastrophic.

I have seen this happen a few times with Glocks.

Just load jacked bullets and avoid +P loadings as the manufacture recommends. All will be well.
