GRW:
I had posted this previously, but my response seemed to disappear....
If you go to Kahr's web site, you'll see a number of decent articles about Kahrs. They have a lot of advantages, particularly for CCW. Kahrs are quite thin, making them easy to conceal. The single stack design also makes them great for people with short fingers -- I know a number of women who carry Kahrs for just that reason. They are reliable and accurate. The MK9, while a bit heavy, can fit in my jeans pocket with a pocket holster (in fact, it's there right now). Prints less than a J-frame.
I have a K9, K40, and MK9. There is very little recoil in the K9. A bit more in the MK9. And I find the K40 to be a bit unpleasant. The short sight radius of the MK9 makes it a bit harder to shoot accurately, but it will certainly do the job if you do yours. I can easily make head shots at 25 ft.
As others have noted, the gun is striker-fired, rather than DAO. Like the Glock, it doesn't have restrike capability (an issue to some folks, but I actually prefer guns without restrike -- but that's another religious war). Glocks have short trigger strokes, but that awful crunchy, creepy, sproing when you finally trip the striker. In contrast, the Kahr has a longer trigger stroke, but it is quite smooth. Think of it as the best double-action revolver trigger you've ever had. It's not heavy. About 6-7 lbs or so. Quite nice, actually. I haven't had any trigger work done on mine. But do get one of the Elite models. The Elite models have a shorter trigger stroke (about 1/4" shorter, IIRC). One downside of the Kahrs longer trigger stroke is that follow up shots are a little slower. Glocks can be shot very quickly, if you can ever get used to the Glock trigger (I've tried, but I can't...).
The MK9 comes with two magazines. One magazine is flush with the floor and gives you 6+1 rounds. The other magazine extends beyond the floor and gives you 7+1 rounds. With the short magazine, you can't fit your pinky onto the grip, so I wrap mine under the floorplate of the magazine. I've found that I'm equally accurate either with the short magazine or the extended magazine.
While I've usually been carrying an M1911 of some variety these days, I think Kahrs are great guns, particularly for CCW.
