Did you get your clerk kit put in by the gunsmith.  I have had one in a 1911 Springfield for maybe eight years or more and it has been excellent I really like it and it's very accurate

  Here's an interesting tidbit the Glock 30 recoil spring assembly fits and functions in the XDS it does hang out a little bit on the front but it fires and cycles fine this allows you to change the recoil spring rate because Glock's have many options in that department. Also the aftermarket recoil guide assembly like from wolf or something like that can easily be modified to be just short enough to fit in the XDS but for experimenting you can just stuff a  Glock 30 recoil assembly in there and it will be fine  .

Lots of people shoot 45 super outta there glocks no problem.hell there has been 460 rowlands on that same platform for years.donno what to tell you. Except maybe its not for you.

If you want more power for the woods, a friend of mine (  flyandscuba ) shoots 45 super thru his XDS 45  for a few years now.no change to anything. After watching him I started doin the same thing. Ive seen no signs of battering yet.altho i dont shoot a lot of them i dont shy away from it either.
   If you just want 10 mm and like projects just cause, i competly understand. But 45 super is equal to or a little stronger than 10 mm so that tells me when you get it together you should have no problems with durability  . Search flyandscuba and you can get his info and chrony results
