I've seen some users blasted on various forums for complaining about poor F&F on these knives with defenders saying that these are just "character marks". I personally disagree especially since you paid a lot more than retail for the knife and wouldn't want it on any knife above $300. My first XM came from a flash sale brand new and had some of the deepest tooling marks in the lockbar cutout I've seen out of 5 XMs that I've handled or any I've seen on pictures. I figured it'd be a hassle to bring it up or contact anyone, but I don't really notice it anymore as the clip covers some of it and the mechanical function of the knife is great. For what you paid, yeah I'd be calling someone.
