Glock has been having problems ever since the GEN4's were introduced. The problems also extended to many of the GEN3's also. Mostly the 9mm but the new G21's and some new G30's are having problems. Here's what they did with the 9mm's,
1. Did not allow enough room in the early Gen4's for the dual recoil set up. Many started shaving plastic from the frames. Modified the frames.
2. .40 recoil set ups in the 9mm's causing all manner of problems. 3-4 redesigns of the RSA's.
3. Didn't fix all the problems so the ejector was changed (336 to 30274).
4. Changing from a "dipped" to a straight extractor. Extractor is MIM. Some are too soft and others out of spec.
Their is a guy over at Glock Talk right now with a burned eye socket from his new G30. Reports of problems with 21's also. Obviously not every Glock made is faulty. But the frequency is disturbing. And don't listen to the "hotter ammo" or "limp wristing" excuses.
The Glock manual says the guns are made to fire SAMMI spec and NATO spec ammo. Hot ammo is just increasing the slide velocity and covering up the real issue(s). If you don't limp wrist your other Glocks and it happens when other people fire it you are not limp wristing. Problem is their doesn't seem to be one set of parts or whatever that fixes every gun. Finally got my 9mm GEN4 G19 working with an APEX extractor and a GEN 3 guide rod adapter. Just a general history of the problems that many try to deny at Glock.
