I had an XDs under the Christmas tree this year. I took it to the range the yesterday and I was very impressed with this little gun. I'm more accurate with this than with my M&P Shield 9mm.
I have it on me now at work in a Remora holster and it's very comfortable and very easily concealled. I will get a couple of 7 round mags in the future and hope it doesn't effect concealment too much. My only complaint is the texture of the grip. Though I'm sure an innertube or slip on grips will resolved this.
