I would recommend the XDm, even over the standard XD. It's worth the slightly higher price. Interchangeable backstraps, match grade barrel and after market parts are as readily available. You might want to visit XD Talk. I have the XDm 4.5 in .45 ACP for over 2.5 years and love it just as much as when it was new. IT is extremely accurate and reliable and IMO, XDm's are the best polymer framed pistols on the market. I added a solid stainless guide rod along with a PRP trigger kit to mine. It is simply outstanding.
