I have a CM9 with two 8 round mags.
2 years with about 1000 rounds.
The gun works flawlessly with the stock mag as well as the 2 eight rounders.
I did have a problem with the 8 rd mags when they were new with American Eagle 124 gr taking a nose dive when feeding.
I found that the bullets were hanging and digging into the inside edge of the front of the mag. After polishing off the sharp edge the mags worked perfect.
In a nutshell the gun itself is perfect for what it was designed for but Kahr should do something about the quality control on there mags.
I have also had problems with the 7 round .40 mags but they were end user fixable also.
I have 2 Kahrs, a CW40 & CM9. I wouldn't part with either of them. If they were lost or stolen, I would buy the same guns again..
Maybe by now Kahr has fixed there mags.
