I've been to the factory a few times, and they have different sections for the different types of guns. It looked like production was in full swing for all models, just demand has grown to enormous levels. I have had keltecs for years, and its awesome to see the demand for their products skyrocket. Not too long ago any mention of the brand would draw a majority of sneers, but now it seems the positive remarks are outweighing the negative ones. OP, they are available, however it seems people are now willing to pay a premium. The latest on GB is at $615! I'm by no means a fanboi, but I have been lucky enough to have Keltecs with no issues, other than a 13 year old sub9 with a worn mag catch spring. Here is a pic of the testing/walkin repair facility. The other buildings are to the right, and they are quite large buildings. The long strip section is a 100 yard indoor test range.
In all reality, I wish I could honestly believe that most people who want Keltec products will get them in a timely manner, but know it would not be true. Best of luck OP on your search!
