"jammed" ? Details please.
Unlike high dollar custom guns, XD's have generous operating clearances right out of the box for high reliability. They don't require a number of rounds to "break in". Certainly, they will become smoother and in many ways better, but you don't need it to enhance operability.
Have you cleaned the weapon after your range run? Take the mags apart too. Poke a sharp pointy object into the hole in the bottom of the mag, then slide the bottom cover to the side. With the mag empty the spring pressure isn't bad. Pay some attention to how the parts come out as they have to go in the same way. It's pretty obvious, but it pays to be attentive.
You may have a hunk of grit in the mag well or hanging from the plastic follower. I just wad up a paper towel and push it through. It's stainless steel and plastic, so you shouldn't use an oil based lube. Use a 100% silicone spray or one that leaves no residue if you feel like spraying something. Fact is, you are just fine running them bone dry, if not BETTER off.
If you weren't already aware -- don't lube the striker. Powder residue will accumulate in the striker channel. It will form a thick sludge like goo that will result in light strike mis-fires eventually. The gun is designed to operate with a dry striker. Again, a 100% silicone or residue free lube if you feel like spraying something. If you have already lubed it with a drop of oil or two, it should have the striker removed and clean the channel and striker.
