I've had one for a couple of weeks, and probably have a couple of hundred rounds through it. No issues or problems. Didn't expect any. I've only used factory, range RN ammo so far.
Side-by-side with the same ammo, on the same day, it shoots a little more accurately in my hand than an equivalent Glock 9, but not enough to get excited over. With the millions of Glocks out there and the billions of rounds through them, its hard to call the XD/XDMs as "Glock equivalent"s, but they're nice pistol at a good price with excellant Customer Service if you need it.
