My serial number is XS551xxx and it was test fired by Springfield on 10-26-12. Is yours an earlier production model?I have had light strikes in every box of ammo. Anywhere from 1-6 light strikes in every box of 50 rounds. It happens with all 3 of my magazines, in random locations in the magazine. The light strikes show a very small dent that is located way off center, and the fired rounds have a nice, deep dent, not always perfectly centered, but moreso than the rounds that don't fire.
Last night was the first time I had any failure to feed problems, which happened twice, and one stovepiped. I don't limpwrist the gun, I can shoot this XDS one handed, left or right, without a light strike, so shooting it two-handed, fully locked out and having it light strike is contrary to the common limpwristing problem many people could legitimately complain about.
When it shoots, it shoots great, but I can't get the gun to stop malfunctioning in less than 100 rounds, which doesn't give me enough confidence to carry it yet. I have put 450 rounds through it, and it is getting ridiculous to be spending this much on ammo trying to proof out a bunch of theories that don't fix the problem.
I have contacted Springfield 3 times about the problem, but they only indicated cleaning it and relubing it, leaving it 'wet'. That didn't solve the problem, and I am still having problems after having sent it back to Springfield. They disassembled it, saw nothing wrong and re-lubed it. They test fired it and it worked; well yeah, I can get it to run for just a few mags, too, usually, but it will have a light strike within 100 rounds.
I normally love Springfield, and have shot them for 20+ years, so this is a frustrating and conflicting problem for me. But I am disappointed in Springfield's dismissing attitude about the problem. I also have a problem with the recoil assembly having nicks on the edge that even created burrs. I sent a picture of that to Springfield and was told it was normal. This was after the first 60 rounds.
The gun shoots straight and handles well, when it does shoot. It is the perfect concealed carry pistol with great features, and most people are having great luck with it, but mine so far is a lemon, and I am getting fed up with spending a pantload of money on ammo just to prove these theories aren't fixing the problem.
