Appreciate the info!Yes, especially if you use the included upgraded spring. Weak ejection and BITF was a big issue 5 or 6 years ago when Glock supposedly changed the geometry or went to MIM for the extractor in Gen3 and Gen4 Glocks. You should get more than enough reading material via a few Google searches. I upgraded a couple of mine that were having the same issues you described, and the problem was solved.
