I hope this means the T/C Encore and Contender G2 receivers are now considered interchangeable i.e. a receiver originally sold as a rifle can be freely converted to pistol form. Thompson has had to register frames serial numbers as rifle or pistol at the factory. It was Ok to build a rifle from a frame sold as a pistol. Building a pistol from a frame sold as a "rifle" was illegal. That was just plain stupid.

So a frame sold as a muzzle loader can’t become a pistol?
