My theory is that customer service is an indicator of the economic prospects of a company. Having good customer service brings customers back and adds to the bottom line, but for some companies it is one of the first things that gets cut during hard times. For example, I give S&W a lot of credit for having very good customer service through their good times and bad (and they sell a lot of guns for economical prices). I think some of the companies that have a reputation for bad customer service may be the next to fold.
So when I hear CZ has good customer service, it is good to hear because it means it will be there if I need it, plus it means the company has good prospects to stay around longer.
