I have used Taurus' Lifetime Warranty twice, once each for my M66 and M44. Shipped off and in a month back in my hands and zero dollars to me, not even shipping and handling. Both work flawlessly now.
My problem is not the Warranty which they have honored, it's the fact that they were both NIB and developed problems after only a hundred rounds or so. So no more Taurus revolvers for me. My PT92 bought in 2000 just keeps on keeping on and on and on. It's a great gun.
