But somehow when Glock releases a model (admittedly, about the ugliest implimentation) it becomes a hot debate.
Well, when you spend decades(?) marketing your existing products as having reached "perfection," then making a change in something that was otherwise consistent (e.g., adding front serrations where none were previously used) necessarily raises the question about whether you have de-perfected the new item. Glock kind of brought this on themselves, no?
