Looked at a gen 5 Glock barrel this morning.

Very impressive upgrades. More conventional rifling and some free bore ahead of the chamber prior to the start of the lands. Also a nice target crown. This was a Glock 45 9mm. I'd bet these would shoot cast pretty well. Anyone try one yet?

G43 shoots boolits well and very little leading. Couple of passes with a dry brush and good to go.

I just picked up a GEN 5 G19. I’ll break it in this weekend, to include some of my 125gr LRN reloads. I’ll report back if there is any leading.
