I own 2 M&P 22's that we shoot quite a bit. Over on another Forum the ftf, fte and double feed issues were discussed at length and most problems seemed to be ammo related. From what you described, my guess is that it is probably the ammo. I bought both of my M&P 22's from my local gun shop on the same day. One of their old time hands told me when I bought them to shoot high velocity loads through them or that I might have the problems that you described and depict in the photo. This, mind you, was before I had even heard of the issues on the other forum. I thought that he was just trying to sell me some high dollar ammo. I had a couple of hundred rounds of Remington Golden Boy 36 grain and went an bought another brick of the same from Walmart. I suffered the same problems although the problem did get a little better after shooting up that 700 rounds or so and after a couple more cleanings. Now I shoot CCI Mini Mags, Wnchester Super X High Velocity 40 Grain, etc. through mine and no longer suffer the problems. I have never had an ftf, fte, or a double feed on any of the Winchester High Velocity 40 grain. Mind you, I clean the pistol after about every 250 rounds or so.
