Update:
So yes, there is a severe lack of availability of the SUB-2000 in my part of PA. I'm putting out an APB for a Glock mag 9mm SUB-2000 anywhere within 50 miles or so of Lebanon. If your local FFL has one in stock, and you're not interested in buying it first (you should think about it!) I'd love to hear from you! I'm not really interested in pulling one off the intarwebs (gunbroker auctionarms etc...) Too much hassle and too much of a paper-trail...
Thank you all for all the help you have provided and all future help too!
