I would fire off a few and then it would cease up with a round half way in the chamber. All I had to do was pull back on the slide a little bit and the bullet would seat and go forward. I didn't lube the gun up before taking it out or clean it after the first hundred rounds becuase it didn't appear to need it at the time... could this have caused the problem or might it be part of the internals? This is my first hand gun so i really can't tell what it could be. Also, the problem didn't persist for the last 40 rds or so I fired.
I have three XDs. I have not ever had any problems with any of them feeding factory ammo. I don't keep them very clean, but I always lube them up. I find that most folks with feeding problems with factory ammo have either week mag springs, or poor lube conditions. Your problem sounds to be the latter.
I suggest a good teflon oil such as Rem Oil or a Slide Glide type grease, then shoot again and again and again. If the problem doesn't reoccur, you will have a very inexpensive fix to a very common problem.
