I said that I would stay out of this, but I will make this one post and then quit.
In and of itself, the lock doesn't bother me that much, and while I don't like it I can quickly fix it so that it no longer represents a problem, other then a cosmetic one - which is a minor consideration.
But revolvers that have the lock also have some other questionable improvements that came about because of production cost issues. While I understand why they were necessary for economic reasons, they still are undesireable to me for various reasons. Older guns for the most part don't have these features, and for that reason I believe I can buy a better product, often for less money, on the second-hand market. This observation is not limited to a certain manufacturer, or exclusively to firearms. Unfortunately the kind of quality I insist on would no longer be affordable (at least for me) in new production guns. I believe that at least some buyers that object to the lock do so for the same reasons that I do. A long lifetime, and the experience that goes with it, is the basis for my judgment.
