Cynthia, I had a few issues to work thru on my CW380. FWIW, here is what I have learned - 1) there is a significant variation in .380 ammo from different manufacturers; European made ammo may have rims that are larger than the SAAMI spec and will not eject properly; Fiocchi, for example does not run well in my pistol. 2) my Kahr 380 has a tight chamber -- I had a box of Remington green box ammo that would not pass the "plunk test". Most quality SD ammo runs perfectly. 3) there is a wealth of information on the forum about tweaking and updating the Kahr 380's - I have looked at most of it and there are some good suggestions that are within my mechanical capabilities, and I have made some updates, but my basic approach has been to test a variety of ammo and keep using what works in my gun. 4) Kahr customer service generally has a good reputation among the forum members, and I would not hesitate to use them. 5) After break-in my Kahr 380 has been a pleasure to shoot - it runs well, is surprisingly accurate, and easy to carry. Good Luck with your new pistol!
