I have a PT92 AF that had the same problem about 5 years ago. The gun was fairly new, and Taurus says it has a lifetime warranty. I called Taurus and they sent a new locking lug. Put it in and it broke TOO! After about 300 rounds. Called Taurus again and they said send the pistol to them. They replaced the locking lug and the barrel for free. I have other Taurus pistols that have not had a problem, but now I am kind of leery of this gun. Anyway don't spend money with anyone else, call Taurus!
