I've owned a CW45 since february. It had a problem with rounds hitting the slide stop, causing jams. I called Kahr, was speaking to a live human being within 2 minutes, and had a new slide stop in my mailbox within 4 days.
The other day, I noticed a burr forming on the front of the right front frame rail. Thinking of wally's broken rail pic that he keeps posting on thr
, I called Kahr. Again, I was speaking to a live human being (same guy, Ian) within about one minute. I explained the burr and why I thought it was developing. I had a free return fed ex label in my email within 5 hours of the call. It is currently in route back to Kahr.
I'm not happy that the gun has problems, but I sure can't complain about their customer service.
I think they are having some QC issues with the CW45, but they are doing a good job of standing behind their product in my experience. I love the way the gun shoots when it's working properly (trigger is smooth!). If the gun comes back reliable, I'll probaly be buying more Kahrs.
No experience with the Nano.
