Sounds like a good excuse to get another gun. Just in case.
Too bad they just can't send the darn part.
This has always been my biggest peeve with the Springfield XD. The fact they won't sell parts to the general public, forcing you to send in the gun for even the simplest of repairs. With Glock you can get any of the 34 total parts in the gun, from literally dozens of vendors out there in gun land. With the XD it's no can do. I actually know a couple of guys at my local club who have 2 of them just for this reason. They shoot steel and IDPA regularly, and can't afford to have a gun down for any length of time.
With 2 if one goes down they can send it in and still have another to shoot with. Something about that just doesn't seem right. I like Springfield, but this is one area they really need to take another look at. Especially with so many XD's out there.
