I was cleaning my XD-S today and noticed the plate at the end of the recoil spring assembly that seats itself at the underside of the barrel was jagged and had some dings. http://imgur.com/a/nfRAT I don't recall this being the case the last few times I cleaned it. I've had this pistol (bought new) less than 10 months. Is this a problem? Is it considered normal wear and tear? It's actually been awhile since I've been to the range but I think this pistol has only ever malfunctioned once on me.
