This is going to sound dumb, but if you know/look up Massachusetts law you'll understand. I'm looking for a glock 19 generation 3 manufactured before October of 1998. Massachusetts is restricted to gen 1, 2 and the rare gen 3s that were manufactured before the ban. Willing to pay more than you'd ever get from someone in another state, as it's rare in MA, and it's definitely all legal (if you're skeptical, I encourage you to look it up). This is a great opportunity for someone who is looking for a new gun or upgrading to a gen 4 to get an awesome payout for the new gun!
