I rented a MK9 a few weeks ago and absolutely had to own one after shooting it. I liked it better than my Glocks and SIGs (P239 is tough to beat) but maybe not my HK P7. The MK9 was accurate, easy on the eyes and didn't seem to be any bigger than neccessary. After searching for a used one I finally settled on buying a new one. When I went to shoot my new MK9 it performed pretty poorly. It was reliable but not accurate at all. The shots were all far to the right and stringing up and down. I wouldn't even call them a group. After 500 rounds I saw no difference. If I shot from a rest and really concentrated the groups got slightly better but still shot far right. So I rented the MK9 I shot before and shot 100 rounds through the pistols side-by-side at 25 feet using a Weaver stance, the same magazine and the same ammunition. Rental gun: nice groups at or near the center of the target. My gun: nothing that in my opinion can be called a group from a $700 pistol. The area highlighted green is the group from the rental gun. The other "group" is from my new pistol. So I photographed the last target I shot and emailed it to Kahr asking for a solution. They stated they would be happy to accuracy test it for me if I shipped it to them UPS air or FEDEX overnight. Both cost about the same; $60!!!! I shipped it to them; what else could I do? I won't even carry the gun as it is now. Experienced Kahr owners, is this normal? This year I've sent guns to S&W, SIG and Magnum Research for warranty work and they covered shipping both ways. I've owned this thing for 2 weeks. I felt I got a good deal on it new but now I wish I hadn't bought it with the extra $60 tacked on. I really just wanted to buy the rental gun but they wouldn't sell it.
