Shop (uspatriotarmory.com) if you've been thinking of trying to build a firearm from an 80% blank, you may have waited too long legally, but Il've been looking into this for a few months and the Sig Sauer P320 can be built this way with a MUP-1 80% blank and a jig. They've both been difficult to find but US Patriot Armory currently has them both in stock. I would not wait if this is something that interests you. Just FYI it's a lot more difficult than the 80% Glock clones, but I doubt you would ever regret buying this, even if you just resell it (UNMODIFIED, of course)
