Heads up, if you’re a Certified Glock Armorer find out who your local or regional manager is and give them a call. I called mine and this cool package showed up in the mail within two days.

This is for a Glock 17 Gen4 (#30274) and took all of two-three minutes to install. My original, crappy ejector was a #336.
Here’s a picture of the new one installed.

So far the new one has fixed my erratic ejection issues, but I’ve only run about 200 rounds through it since replaced. That was a combination of Wally World WWB and reloads.
