So far the trigger is still stiff, but the take-up seems shorter than my stock XDs. Accuracy is good, but so are my other XDs. Sights are better than the old stock XD sights.
Shooting in 90+ degree weather, the grip was still slick, even with the new design. I've got skateboard tape on all my other XDs, and may have to add it to this one as well. The new design wasn't "too agressive", as others had guessed. It did not tear into my hands at all.
I like the recoil of my XD-40 5" better. It has a 22# spring and a Don's Guide Rod from Pistol Gear. I may make the same changes to my XDm, after it's broken in. Who knows, it may grow on me as-is.
