Hello from sunny Baghdad! I know that I'm going to buy an XDM but I'd love to hear the differences between the 9 & 40 from an owner such as yourself if you'd oblige. It would be for both my wife & myself, as it's our 1st personal gun (we're both in the military). I've asked quite a few guys here about their feelings on the difference in caliber & everybody has been talking smack about the 9 so as of right now I'm leaning heavily towards the 40. Thanks so much for your time & please, no rush, I'm not going anywhere for a couple months.
