I was caught a little off guard when field stripping, cleaning, and lubing mine up yesterday. Was also doing it with my 4.5 9mm XDm, and definitely noticed some differences, mostly in "ease."
The XDm, or at least mine and every other one I've ever used and field stripped is much more cooperative, don't know if this is just because it's been out longer or what.
Being left handed, I for once noticed a little bit of difficulty with the slide that I've never noticed on any XD or XDm. Half the reason why I like the XD/XDm platform is because of it being ambi mag release and how "easy" it is on us lefties.
That's okay though, I'm used to having to "adjust" from my time in the Army

Just caught a little bit off guard..I still like my XDs a lot.
