I called SA and spoke with one of their top techs hoping that they might have some insight since some people have sent theirs in. Here is what I found out. The off center strikes are due to the gun not going properly into battery. This is due to improper lube. SA has received 7 XDS's to date and has shipped thousands. None of the 7 have had off center strikes once properly lubed. SA put 150 rounds of various brands to test this in each pistol. There is a small chance that it could also be grip related. A limp wrist will cause battery issues. Related to above. It WILL fire when not in full battery. There is a buffer there due to dirt and grime maybe causing a slight out of battery. It will never be "100%" in battery, so there has to be a hard line between not firing and firing. In this case it is just barely out, allowing it to still fire, but causing a high strike. The way I look at this is that people will never be happy. If it does fire micro meters out people think its a flaw. If it didn't people would be pissed about its reliability. Also people are getting so caught up in Potiential issues they don't stop to think that any gun would do the same thing. Striker pin damage. From what they have seen, everything is normal. This includes the 7 sent in and the pics from these threads (which they have been monitoring). There has been one that has more of a "dent" than normal which was due to some one taking the striker lug inside the slide, fully retracting it, and letting it slam, several times. I speculated to this yesterday when someone posted a pic of there striker that was said to be "perfect". It still had a slight dent. when people say "Mine is damaged" or "Mine looks good" we have to consider that our definitions are different. What you call damage, someone else might call good. Bottom line is that every pin will have some sort of dent there. Due to the fact that it is a floating striker, that part does indeed rub and vibrate against the striker safety. The wear is almost immediate, but COMPLETELY NORMAL. It is no different than wear that piston rings create on a cylinder wall in a motor. It creates a tight bond. Every striker is molded without the dent so that it can break in perfectly against the safety. Again people are quick to jump on this wagon of pin issues. No one stopped to google search and see that Glock pins have the same wear. Fail to Feed's are somewhat resolved already. It's is becoming known that the XDs requires a very powerful cycle. Casings pinging against the slide creating marks. This is unavoidable. The casing if seen through a slow motion camera comes out spinning. An no matter the grip or control of recoil, they sometimes hit the slide. Hopefully this will settle the concerns. There have been about 6 threads talking about the same thing. They have all blended together with some people even copy and pasting the same posts in multiple threads. People are calling for recalls, trolls are making up stories, and we are giving the XDs a bad name. We jumped the gun so to speak and started all these surveys and theories. Any wonder why the FTF Serial # still doesn't have a clear trend? The gun is fine.
