I fit that rare category: I'm a relatively new shooter (~2.5 years) and live in the Peoples Republic of Massachusetts. Glocks don't meet our AG regulations so they are only available in face to face sales and tend to carry a price premium.
Have you tried a Volquartsen Edge Extractor? My regular MkIII was flawless since new but my 22/45 couldn't get through a mag until I replaced the extractor.
