Number 1:
Must fit 3.3" XDs. Must be OWB, with thumb-break, or similar retention. It should be brown leather, but I'd consider kydex. Budget is ~$50.
Number 2:
Same gun; same price range. Must be IWB with single, tuckable clip. Must be rigid; not some shapeless bag.
#2 -- I got one of
these, as an upgrade from a Blade Tech Klipt*. It hits all your "must be" points. I like it a lot.
The options I got (full height sweat guard, AIWB "claw", extra optional belt loop in case the the clip didn't hold reliably) bump the price a bit. The default clip turns out to hold very well. I wear it at 3 o'clock, not AIWB, but the claw thing bears on my belt and pushes the gun butt up against my side --> less printing.
Tell him I sent you. Maybe he'll give me a break when I order something else.
*I'd just give you the Klipt, but it's not tuckable.
I'm not saying there are no XDs holsters out there, but it doesn't seem to be a gun that everyone's rushing to make holsters for.
The G43 and S&W Shield is the current hotness. And, it seems to be popular these days among some in the Internet Gunsphere to run down Springfield's plastic offerings.
