I shot 50 rounds of MagTech FMJ and 25 rounds of MagTech JHP 95 grain std (not Guardian Gold).
I had 3 FTE. They were jammed half out with the next round jammed under. This is the first ammo that has had FTE issues in my P3AT. Each time it occurred with the same magazine and occurred after the 3rd or 4th shot. It may have been coincidence since the brass does not seem to be uniform. The rim groove appears to vary from round to round and even on opposite sides of the same round. I don't plan to buy any more of the MagTech.
The rounds that did eject still have the telltale sign of the flattened side. I did notice that the flattened side appears on the right side of the round as fired just below were the extractor grabs it. I originally thought this was caused by the ejector but the flat area's location in relation to the extractor marks makes it appear that it strikes the lower edge of the ejection port during ejection. There are also brass marks on the lower edge of the ejection port.
The first image shows the brass from three fired rounds from left to right (Fed Hydrashok, MagTech JHP, Hornady XTP). The MagTech rim cutout is not uniform.
The second image shows the brass from two MagTech rounds that extracted Ok. Notice the location of the flattened side (Yellow Circle) in relation to the extractor marks (Blue Circle). I'm not sure what causes the ding indicated by the green circle.
The third image shows the extractor marks of a MagTech that failed to extract. There is no tear in the rim so it does not appear that the extractor had a good hold on the rim when it slipped off. Notice again the nonuniform rim groove. It appears to slant down left to right with the right side having a steeper shoulder.
Fourth image shows the barrel port with some brass marks. This is what was left after a light cleaning. There was more brass before the cleaning.
