About 10 years ago, I purchased a S&W 6906 and a Taurus PT92, within a month of eachother. After owning both of them about 6 months, I received a letter from Smith, stating they were having problems, with stress fractures, developing in the slide rails, which could lead to a failure. Now mind you the Taurus at the time had 3 times as many rounds through it, than the Smith ( I had 3000+ through the Taurus ). Anyway I sent the Smith in, they notified me, they x-rayed it and it had started to develop the stress cracks, and it would need to be replaced.. They sent me a new one, which I promptly sold 3 weeks later. The Taurus I had for another 8 years, with god knows how many rounds through it, problem free. I had to sell it due to some financial difficulty, about a year and a half ago, man I'd love to have that gun back, I know I could just go buy a new 92, but it's just not the same.
