Well Monday my 22 compact wasn’t extracting all the time. So I called Smith and they said here we will send you new parts. So nice. Then last night I removed the bolt block. And took it apart. Dumped the parts in ultrasonic cleaner. Then for fun was putting it back together. Uh the firing pin isn’t a 2 part pin now is it. Oops call back to SW new firing pin added. So after 23,000 rounds of cheap bulk crap worn extractor and a broken firing pin. Never had issues with the rounds firing.
