I am the one who made that video.

I have put over 1000 rounds through my gun since I made that fix without any FTE's. In talking with others who have sent their gun back to S&W it appears that is all they are doing is bending the ejector outward and sending it back to the customer. The one benefit you get from sending the gun in is you will get a couple of magazines. I didn't want to be without my gun so I chose to fix it myself.

The other problem with this gun is the occasional FTF. Most of these can be resolved by just loading the magazine correctly. However I have a fix I copied from another member here for the magazine and haven't had a single FTF since and that was over 400 rounds ago. I am going to post pics of that later.
