I did not have time for a thorough test on accuracy, but I did pop over into a shooting bay and dump a few rounds through it.
I LOVE IT.
VERY comfortable under fire; I'm actually wondering how it can be so. I fired one Federal Hydra-Shok and then several rounds of mil-spec hardball.
I will test more this week. I promise. Targets and everything!
I think the grip angle is making the difference for me. The Glocks are okay in the 17 and 19 frame, as long as I make a conscientious effort to push the muzzle down, but the diminutive 36 wasn't as comfortable doing so.
The XD(s) .45 is the most perfect gun of this size I've ever laid my hands on. I've not shot the little Kahr .45's, though, but I do have their K9, K40, and CW40. The .40 is not my favorite round, especially in a tiny gun.
Interestingly, the holster that comes with this XD(s) says on the back that it fits the XD(s) in .45, .40, and 9mm. I guess we can expect more calibers in the future.
