Vedder makes great IWB holsters. Go to their site and select the handgun of your choice. They offer IWB holsters for the XDS Mod2. I believe since most holster companies sell specific holsters for the Mod2 and the original XDS that there might be some difference in the holster for each.
I’ll second Vedder. I have several of their holsters, both kydex with claw, and Comfort Tuck series and they’re all solid. They are advertising a 10% coupon code right now. They also have an eBay store for returned items, some at pretty decent discounts.
I like Alien Gear too.
Both sites allow you to narrow down to what your specific needs are.
