The CM45 has been my Every Day Carry for 3 years now. Its a great little pistol. I had one stoppage around round 50 or so during the recommended break in. I have never had a failure since in over 900 rounds. Reports are they can be finicky with anything but a round nosed type bullet, so I carry Remington Golden Saber 185 +P in mine. Use the slide stop lever to chamber a round from a loaded magazine, instead of the "slingshot" method. I have had mine fail to chamber when slingshotting, and Kahr recommends using the slide stop to charge the pistol. Shoot the recommended 200 round break in. Use gloves because its pretty stout being small, and light.
I really like mine. I like the trigger, and the size. I carry mine with the 6 round extended mag, and the 7 round extended as a backup. 1911 mags also work in the Kahr 45s
