Check your local laws carefully! How ironic that in Komifornia you can buy a G2 209x45 rifle get your receipt and DONE!!!! No 10 or 14day waiting period, no FFL paperwork. Yes, I've bought 2 now from different dealers. Same thing both times. But wait.... you can't buy the G2 pistol. It hasn't been drop tested at $5K per configuration like these dumb yutz's want. Not sure about the regular rifle yet, hadn't tried to get one of them.
Point is everybody treats Black Powder differently, talk to your local FFL for the low-down!
