@valleyforge Something makes them a fraction more expensive. Typically the cam block is on the bottom and is removable. Leaving the 1912 Steyr-Hahn aside, the only successful rotating barrel pistol is Beretta Px4. I think Grand Power is perhaps the 2nd most popular/common. The Boberg/Bond is an expensive and weird boutique, Glock 46 is in a very limited production, GSh-18 is endemic to Russia. The lack of the rotating barrel guns makes finding a rotation isolator for a suppressor a difficult proposition, and nobody makes isolators because there aren't any rotating barrel guns.
