Loved my Silent Thunder that I bought for my PM9 so much I ordered one for my XDM as well, again - very pleased! Wearing my XDM Compact IWB comfortably for the first time and finally feel as though I can wear it daily.
If you're in the market, I highly recommend them. There's something about leather lined Kydex that makes it a perfect match. Stability, silent/smooth draw, great looks and my guns seem to love it too.
