So, I was out of town with my wife this weekend and went to a gun range while she was getting her hair done. I rented an XDS and got 50 rounds of .45 to shoot for a little while. I own a 5.25 .40 XDM but have wanted to try the XDS. I set up, load the gun, pull back the slide, and try to shoot. Nothing. Hmmm. Okay, maybe there's a safety or something on the XDS that I don't know about? Try again, and again. Finally, I give up and, in keeping with the range rules, leave the XDS there pointed down range with the magazine out and get the range master. He looks at me like I'm nuts, goes and tries it himself, and has the same issue. He tries to tell me that I'm not pull back the slide fast enough as it's not slamming back all the way. Okay, fair enough, I try that. It fires for awhile and then jams 3 more times during my ½ hour. On the last time, it took him about 8 minutes to get the bullet out as it was pretty stuck. He ends up not charging me for the rental of the gun and says that he's going to ship it back. Is this common? Maybe they're not cleaning it well at the end of each day? I clean my XDM after every range trip and haven't ever had a single jam (about 600 rounds through it so far). It was Federal FMJ ammunition (can't remember more than that). I've thought about getting an XDS at some point but now am hesitant.
