I have carried one for 3 years now. I love the gun. I love it so much that I have purchased 2 more! Mine are all of the XS variation. The one I have carried for 3 years is going off to Accurate plating to have a matt chrome finish applied to the frame and mag release. The side that is against my body is looking pretty bad. I will leave the other two in their factory cases and carry a Kahr P9 while it is gone, but will anxiously await its return!!
I've had mine since January 98, a couple weeks after they came out.
I've changed a few things (grips, safeties) but nothing was really required. At this point, I'm in need of refinishing but other wise good.
