Upgrading your Polymer 80 Ejector can often quickly fix problems related to “spent casing” extraction.
There are tons of small details that can come to light once you go to shoot your newly built Polymer 80 pistol at the range.
One of the more common issues found with the P80 brand of handguns is ejection problems.

Common Polymer 80 Ejection Issues
There are several issues related to a bad or poor ejection that you may face, including:
Failure to Eject
Your Polymer 80 pistol is not entirely removing the spent (or shot) casing from the slide of your pistol.
You pull the trigger, and the casing remains lodged in the barrel of your P80.
Round Ejection Trajectory
When you fire your Polymer 80, the casing is ejected vertically up or to the rear of the pistol towards you, which is not ideal for staying on target after the first fired round.
Slide Rubbing on Ejector
If you have a slight out-of-spec issue with an aftermarket ejector, this can also cause your P80 to have issues with spent casing extraction.
Weak Ejection / Extraction
This can be very annoying as your Polymer 80 is almost functioning perfectly, but the casing is not cleanly ejected from the Slide leading to occasional “jams”.
How to fix Polymer 80 Ejection Issues
Two fixes can remedy slide extraction issues right away.
Fix your Grip
Grip your Polymer 80 frame as you mean it. Many new shooters are prone to “limp wristing” their pistol, and when you do not firmly grasp your Polymer 80 with a proper grip, all of the above ejection problems are possible.
Remember you want as much hand to the polymer as possible. Think surface area and physics.
Upgrade your Polymer 80 Ejector
The most straightforward fix is to drop in a guaranteed in-spec Glock OEM ejector that has been proven to work.
At the very least, you can cross out the ejector as the main issue if you still face extraction issues.
You can also upgrade to a premium “fail safe” ejector that will pull on the casing with increased power to ensure spent rounds are sent in the correct direction post-firing.
