Sadly the problems I had with my 2.0 pretty much caused me to stop shooting firearms as a hobby as I was tired of playing amateur gunsmith to troubleshoot problems.

However, I did get the 2.0 that is the subject of this thread back from S&W and have fired 540 rounds through it without a malfunction. They replaced the extractor. I would want to put another 1500 rounds or so through it to really claim that it's fixed for good.

The luminescent paint on the front sight (trijicon hd) fell off after I got it back. Not S&W's fault, but I pretty much stopped shooting altogether because something always seems to be going wrong.
