A buddy of mine bought a CW9 about four months before I bought my CW40. His has been great mine has been a headache. We both carried Glocks as off duty guns before but wanted a smaller gun. My two hundred round break in period was hell. It went like this bang **** slap rack squeeze bang **** slap rack re rack drop mag unload due to lack of locking reload squeeze bang **** on and on. I have finally emailed Kahr (after cleaning, lubing, changing ammo, and changing lube) for a confirmation to get it checked on or a new part. It seems the slide lock spring causes this. I actually joined this forum because of my troubles with this gun. I will tell you how the customer service goes with Kahr. Hopefully you will not need it.
