Okay don't panic,, like the other poster asked ,,how many rounds thru it so far,, the booklet does say it NEEDS a 200 round break in,, but I have found with their poly version some times more along the lines of 400 make it work well,,,
WHat kind of lube and how heavy did you lube it? Its not like glock,its more like the SIG,, lube it a little heavier than norm when shooting long strings,,
If after that its still doing it then you need to send it back
