Your Walther P22 has a lot going for it. Its grip is about the most comfortable factory one out there, and the trigger isn't all that bad right out of the box. Unfortunately, it has a bad reputation when it comes to its ejector. The only way to solve the issue is to get rid of that terrible factory Walther P22 extractor.
While stamped steel extractors certainly wear out, the P22 seems to be a failure right out of the box. By installing a Volquartsen Walther P22 Exact Edge Extractor you clear up this issue once and for all. Its superior design gives the Volquartsen a head start before it's even heat treated. Side by side you can easily see the longer hook which gives it a much more positive grip on the casing to ensure extraction. The factory Walther P22 extractor will never even come close to the consistency that the Volquartsen brings to the match.
How many times does hot brass wind up in your face, down your shirt, or branding your forearm? Well, that happens to a bunch of people when they fire the P22. The Walther P22 itself is a fine pistol it just needs an edge, an Exact Edge that is. If you like everything else, then don't you dare get rid of that gun. Instead, you need to simply to upgrade the factory extractor to a Volquartsen Walther P22 Exact Edge Extractor. Instead of in your face, the brass flies out of sight. So, you can save some money, keep your pistol and just add a Volquartsen extractor to the mix.
