Friends, I ran another 150 rounds of Tula in my XDS and somehow managed ELEVEN failures to eject. Let's have a look at the photos: Empty case in the chamber, new round smashed up against it holding the slide open. Again. And again... You get the idea. Each time after clearing the malfunction, I put the empty shell casing in my pocket. Here they are: Current theory: UPDATE: Weak Extractor - Springfield Armory wants me to return the gun for service. I did label the two magazines to see if the problem was mag specific. It wasn't. I switched from the XDS to the XDM for the remaining 100 rounds. After the XDS, an XDM feels like a target pistol! Check this out: When I got home and cleaned both pistols, I found the XDS was filthy and the XDM was much cleaner. Perhaps some of the Tula was dirtier than the rest? I do remember one ten round string smoked up the whole range. Might have gummed up the chamber causing the casings to stick? Hope this was just a fluke and that the XDS proves to be as dependable as it's big brother. I've got 500 rounds of Freedom Munitions on the way. We'll see what happens.
