I have yet to have a single firearm I have purchased, with one notable exception, have a reliability issue that wasn't directly caused by something I did. Not saying it doesn't happen, such as the poor fellow with his 8 defective rugers, but as a whole I'm still not convinced that between the major manufacturers there is a *statistically* significant difference in "quality" when it comes to reliability. That being said, the same rules always apply, make sure any gun works before relying on it and I have my band preferences. Also, you shouldn't worry about rust resistance IMO if you properly maintain and clean it. As I sit here typing this I have literally a 100 year old WWI luger on the desk with most of its original bluing.
Also, you shouldn't get upset that someone may accuse you of being a troll when you come on the S&W forum and open up a thread about Ruger quality with no evidence, or even a personal anecdote. It's like going to a tech forum and starting the AMD vs. Intel debate.
