It just really seems to me that there are far too many complaints for this to be simply a small part issue. Sure, they may contribute, but by now enough users have made enough replacements without solving the problem that I believe it must be deeper. Rather than blindly defend Glock's old reputation, and flame users for supposed grip or ammo failings, we should look at the real mechanical issue. I too have older Glocks that I cannot make malfunction, even with crap ammo, filth, or by holding the gun upside down with only thumb and trigger finger. Something must be out of whack - call it tolerance stacking, bad QC, worn out dies, etc. Replacing an extractor or prescribing certain ammo is like telling you to get softer tissues when you have the flu to cure your chafed nose.
