More than likely they have the equipment still but the main components are dedicated to production of something else and the specialized stuff is in storage. From a company standpoint it makes no sense to eat up valuable production floor space with ideal equipment not in use.
From a production standpoint I would think that the size order necessary to do a new run of 3rd gen pistols would have to fairly large to dedicate production time, resources & materials, and personnel to for something that their profit margin probably isn't that big on. Let's face it plastic guns are very cheap to make in comparison to all metal guns.
With that being said it still doesn't mean that I wouldn't like for them to do another run of 10mm's to statisfy my selfish wants.
