Got to the range with my agent recently and I'm worried I might have bought one with a bulged chamber. Gun shoots fine but extraction is diffucult even with light loads. Inspection under a bright light with magnification I can't see any defects. All chambers are spotlessly clean with no obvious defects. Is it possible one of the chambers has a bulge not visible to the naked eye? Is there any solution other than a new cylinder? I don't have a lot of money tied up with this little gun but would hate to think I got taken. Any suggestions or solutions would be greatly apprecieated.
