I agree completely. The key to this is the word trend. Sig P210s do not have a trigger block failure trend that would be easy to demonstrate by posting a few threads with people complaining about them.
Over the years I've sent a few pistols in for warranty stuff, but I was unable in all cases to find evidence on the net of a "problem" with any of them.
I'd contrast that with the "front sight falling off problem" or the "locking block problem" that some models seem to have a reputation for.
In your case, I'd encourage you to remember what went wrong with those guns, do a quick google and post anything you find that sounds like it happened more than twice.
Think of this as a statistical exercise attempting to disprove any and all pistols of being largely problem free.
