I got a chance to take my new MK9 outside city limits yesterday to break it in. The mister and I took two boxes of Winchester white box and a box of Federal HST hollow point to try out the extra +P.
After I shot a six and seven round mag each, we took turns and traded off magazines every once in a while.
Of the first 200 rounds, 7-8 were light strikes. We considered that they might be light loads, but we checked where the striker hit, and there was just a dimple. In fact, we took a few of them and shot them out of a Walther P99 just to see if they'd fire, and they did.
At least 6 of these light strikes happened on the sixth round, whether it was the six or seven round magazine. (Yeah, I know - even with the extended magazine, it was the sixth round and not the last one. I'd take the magazine out to clear the gun and there'd be one left in it.) Only once, there were three bullets left and not one, and it was with the seven round magazine.
All of them happened when I was shooting it, and not he, who is a seasoned shooter of several years, versus my measley two.
He did, however, have a failure to eject around round 180. By this point my gun was pretty gunky and we assumed that was the reason. A little corrosion had started to form on the frame just below the slide lock, and above the trigger area.
After those, we ran two magazines (a six and a seven) of Federal HST +P through it. There were no misfires with it, and it sure added a kick! Dang!

Overall, the gun loosened up quickly. After the first four or five magazines through it, I could tell the rough edges were getting smoothed out. The ejection direction remains pretty erratic, though. About 3/4 of the magazines I shot had a spent casing that hit me in the forehead at least once. At this point, I was also not convinced that it was going to fire every single time I pull the trigger.
Another concern I have I didn't notice until I was inspecting the spent shells. The striker pin doesn't hit it straight on and leave a round mark. It seems to hit and then slip a little, causing a...uhh...skiff mark of some kind.

Also, on the other end of those shells, it looks like the extractor or something has pinched the shell causing two sharp indents along the edge. We checked (by taking the slide off and reinserting the slide lock and a loaded magazine) to see if the slide lock was hitting the bullets. It doesn't, but boy, it's close.

Given both the tendency to light strike or have a bad connection, we decided it would benefit us to really detail the gun and break down the slide to give it a good cleaning. Last night, we cleaned our guns when we got back from shooting, but it was just a basic take-down and wipe out, for the most part. Today though, we took canned air and blew in the hole in the slide and LOADS of wet brass and black came out. We followed the How to "Detail Stip" the Kahr Slide post from the Glock forums. By we, I meant he did - he had taken down quite a few different guns and his curiosity won out on me doing it myself. He was really impressed with how complicated the slide was in the MK9, but even more taken aback by how dirty it was. Like, expletives were used as adjectives - it was that packed with stuff.

We ran a 22 bore mop through it and pulled out lots of shavings and carbon. He wiped it all down with CLP and let it sit for a while, then really wiped it down with a cotton cloth and put it back in without touching it. He dubbed it "cleaner than a skeeter's peter" and we dry fired it. The stiker seemed to hit a lot harder and less gummy, that's for certain!

So, summary: a few light strikes, and one failure to eject, but I figure that's due to how dirty the striker assembly was. How many rounds does the Kahr factory test fire in a gun before it's packed up and sent out?
I'm excited to go shoot it again, now that it's so clean I could eat off of it.
