Yep, buy a new one. More meat around the pin, updated springs in mag & recoil, updated extractor & extractor spring, tougher finishes, and a factory warranty make the new guns a better choice for shooting / cary. Also there are CRAZY people out there willing to pay higher prices for a used Farmingdale than a new Deer Parker would cost you. I happen to fall into that group My carry gun is a newer model but as collectors I love the early Farmingdale models.
Eithor way there awsome and welcome to the forum.
