Hi,
I've noticed an oddity with my new Gen 5 19 MOS. I've tested the following method with a Gen 3 19, Gen 4 26, G43, Gen 5 19, 19X, and Gen 5 19 MOS. The new Gen 5 MOS seems to cause a strange extraction/ejection issue. To all Gen 5/Gen 5 MOS users, please try the following and post your findings.
The Test: Load a round into the chamber and then slowly pull the slide back to extract/eject the round. Try this with and without the magazine inserted. When I do this with the Gen 5 MOS, the round gets hung up and will not be ejected with ease, it just stays attached to the extractor. The only way to eject the round is to cycle the slide with force. I noticed this issue when I was dry firing and tried clearing the chamber and the round would not eject.
When I do this with every other Glock, the round is pulled out by the extractor and glides right over the ejector causing the round to fall out very easily. Using my current sample size, I imagine this is considered proper ejection and extraction for the pistols. Also, I've never had a single failure with any of these pistols that exhibit this behavior.
This is where I request the help of PF. I swapped out the extractor and ejector with my older Gen 5 19 thinking that would solve the problem, but it did absolutely nothing. The older 19 uses the 30274 ejector and the new MOS uses the 47021 (as does the 19X). I then placed the MOS slide on the older Gen 5 frame and the issue remained. I placed the older Gen 5 slide on the newer frame and the gun cycled perfectly. Using this data, I believe I've narrowed the issue down to the slide. Is it safe to say my slide is out of spec or is this considered proper function?
