Once again. Taurus guns are well designed (where they differ from other makes) and are made with excellent materials. The company's weak point is in production. Toyota has given a lot of publicity to the idea that quality control begins on the production line, with machine operators who have the authority to stop production if they see something wrong. That might not be strictly true, but Toyota has a good reputation for quality.
Taurus either does not do that or their workers don't care enough to watch what they are doing. The result is predictable, Taurus quality control is spotty. Those customers, the vast majority, who get good ones, will have as good a gun as any on the market. Those who get lemons will tell the world, loud and clear. And Taurus has a lot of lemons, far too many.
As for customer service, if quality control worked 100%, there would be no need for CS. If it doesn't, CS will be swamped and unable to deal with all the problems that arise from poor QC. The ideal CS is the Maytag repairman, dozing through the day. Again, maybe not strictly true, but an ideal.
