I had to send a taurus revolver for service last year. It took about 6-7 weeks from beginning to end. They did some extra work on the gun, also free, so the wait wasn't too bad. My son had an issue with a PT1911 and had to send it to the repair facility. About 5 weeks, and they threw in a new magazine for his trouble. In short, it is not blindingly fast, but the work was done well and there was no problem getting Taurus to honor their warranty.
Frustrating to have issues with any weapon, but problems with mechanical devices are inevitable. Good luck!
