    I reload multiple calibers. Most brass I recover in other calibers besides 10 are in pretty good shape. I notice with my 20 and 29 that the brass gets really scratched up. Frequently the rim has heavy scratches that I'm sure can cause function problems if I reload them. Yet the 20, at least has been back to the factory and the extractor replaced.

    Does anyone else encounter this with their Glocks?

    What power recoil spring are you using? A heavier spring might reduce slide velocity somewhat. You might check for burrs on the extractor. I chipped off half of a G20 extractor doing the 200 grain bullet at 1200 fps with AA#9 test. I use a 22 lb spring normally but I have a 24 lb for hot stuff in the G20. I have a 21 lb for the G29. I see Wolff has a 23 lb now.
