No, it has not influenced me ....
Because, to date, I have seldom seen anything bad about the guns I am interested in. There are lots of guns I simply do not care about, and have no plans to buy, ever. So I don't care if brand XYZ models 1,3,5, and 9 have crappy parts, or what ever the problem is.
I don't like S&W models with the lock, not because I am worried about one engaging on its own, not because of internet tales (true or otherwise), but because I am disgusted with the change to the look of the guns. I dislike the hole in the side, and the new shape of the cylinder latch. That's why I buy pinned & recessed S&W, and no others.
When ever I have the chance, I do shoot models of guns that I don't own, and don't plan to. Just so I can have an honest basis for my opinions. And every once in a while, I do get suprised, and something I though wasn't good turns out to be ok. Still doesn't mean I will buy one, though.
Most of the time, shooting one just confirms why I am not interested. I do find the Internet reports of trouble of value, as well as interesting, but so far, I have not found any that actually influenced my purchasing.
