Tecolote -
You'll have to admit your first reply just didn't have a whole lot of "can't we all just get along" in it.
We could probably go around and around about it, but Glocks appear to have two or three small parts with a very short MTBF. I will cite the Glocktalk "Clubhouses" again, particularly "Big Dawgs," "Ten Ring," and the "Top Guns." (I'll admit you see a whole lot less of in "Niners.") If you spend any time at all on those forums, you'll be surprised about the number of these small parts they seem to break/replace regularly, and just take it stride. (If some the stuff they post over there was posted on TFL, there are some users that would absolutely crucify them--they can actually admit their guns kaboomed and talk about it without fear of tar and feathers.) Again, my advice is to accept it, make it routine to check/replace them--they are inexpensive and easy to replace. Why take a chance on a failure at critical moment?
(And if that is taking a jab a Glocks, you are a sensitive spirit!)
