^ My son still has the PHK- and a PHP- Gen 4 G17s purchased in Spring 2010. Both continue to shoot superbly in original configuration - round counts 12K and 4K. Extremely accurate and w/o BTF. So your's may be as good. Or you may be looking to Glock for a current extractor and ejector upgrade. Are you familiar with the new Gen 4 9mm ejectors?
