As the title says, i own an XD9 Tactical Model (produced 2011) and have been having some serious ejection problems. Its had just over 3000 rounds through it (most of them steel cased wolf) and recently the ejection has became very erratic, it varied from just barely dribbling out and falling a couple of inches from the gun to landing consistently roughly three feet on the shooting bench i was resting it on and everywhere inbetween. Firing position was on sand bags inside the red circle. the ejection was that giant pile of steel cased ammo. 250+ rounds fired Now you could think i limp wristed it and the lack of rigidity was not giving the slide enough rigidity to fully recoil and kick the case out correctly, but the recoil impulse was similar to shooting wolf prior to this outing. Plus i had a second XD9 to compare with (a sub compact Produced in 2003) and it ran perfectly fine on the same exact ammo! The fact that the recoil impulse felt the same and the ammo worked fine in another XD, lead me to think that the problem with ejection was rooted to the extractor/ejector. when i broke the gun down to inspect it on the range i noticed a gouge in the ejector as well, the extractor had no abnormalities. From what ive seen on my XD is that the gouge on the ejector is from the Mec-Gar 18 round mags i recently bought. (Witch i love by the way, and just bought another) Below are some photos of the factory mag and the Mec-Gar mag in both "pressured" or "pushed up" positions and the "rested" position. in the photos its clear the space between the feed lips on the Mec-Gar mag and the ejector is much closer that the factory mag, also the spot its nearest to is were the gouge is located. Factory Mag Rested Factory Mag Pressured Mec-Gar Mec-Gar Mag Rested Mec-Gar Mag Pressured The gouge was present after the first range session with the new Mec-Gar's so i am pretty confident the new Mec-Gar's that have altered by ejector. but it could just be the wear of 3000 rounds(mostly steel) changing the angle on the ejectors face. The red lines on the images below are to "highlight" the worn areas The face of my ejector is not pictured however it has became worn on half of the face (the bottom half) to a point in with it has possibly changed the angle. Top view of the ejector Right side of the ejector Left side of the ejector with the gouge My XD subcompact on the other hand has very little wear on the ejector and contains the old style ejector that is much more substantial, and heavy duty looking. most of the wear on the machined (MIM?) ejector is on the bottom of the ejector were the mag's feed lips make contact. Older machined (MIM?) ejector on the LEFT Newer stamped steel ejector on the RIGHT I was looking for a ejector replacement and i found this one made by Powder River Precision PRP EJECTOR Witch resembles the older machined (MIM?) ejector found in my subcompact, although the PRP is machined 416 Stainless Steel and is heat treated, If you have any experience with the PRP ejector or with what determines an XD's ejection pattern, or have even had ejection problems in your XD orXD(m) and have resolved them feel free to chime in. at this point i'm just hoping its not the extractor cause that results in a guaranteed trip to Springfield. Thanks for any advice or insight on the matter.
