I have a new P229 Scorpion 9mm. Just bought it at NW Armory last week. I took it out shooting today and noti ed that when it fires, the slide doesn't cycle at all. So the shell doesnt eject and the hammer doesn't go back. I have to manually cycle the slide to shoot again. The gun is new, but I thoroughly cleaned it. Still same issue. Then I noticed the shells are deformed when they pop out. I know that's bad, but I'm not smart enough to diagnose it. Take a look... the top of the shell is totally bulged out. What do you think this means? Should I take it back to NW Armory or contact Sig directly?
