Fixing Glock G17 Gen3 ejection perfection.

Glock introduced changes due to Great Non-Recall Product Upgrade which led to the Gen3. Also, they flared back the port and extractor, and new extractor had extra outboard mass of loaded chamber indicator, and it was/is MIM vs machined casting.

End result has been folk bugged by incosistant, lethargic or whatever ejection, sometimes in face, other times right back down in port to jam the gun. They have bought all manner of aftermarket extractors at three times OEM price, trying to cure problems.

I invented none of this, and only addition was to also swap for the still available non-LCI extractor and associated plastic plunger spring parts. The old style simply a better looking extractor with more sharp edged/hooked bite.

Alone, it improved lackadaisical ejection, somewhat.

The new Gen5 19X has a new longer ejector #47021, stuck in the trigger spring housing (assy has own part #) for same 19X gun, where the standard new G17/19 still uses the old one. Likely that a voluntary change, same as to the still available Gen3 G17, would be an admission of fault or defect, and them liable for upgrades to a bunch of dept contract guns.

The new housing assy needs be obtained, only to rob the ejector, and it placed in the G17 housing.

This video shows only the ejector swap difference, both earlier style ejectors, plus the latest 19X ejector, two types of ammo used for each ejector.

It works, and more as a nicely tuned gun, rather than ultimate random reliability.

Only passing this along.
