I haven't seen any for pistols. When the 17 Mach 2 first came out there was work done on making a 10-22 conversion barrel, but as the project developed there needed to be different action parts as well. I lost interest and don't know where that led anymore.
Eabco had a barrel and bolt handle set that was supposed to work. Maybe they have something for this as well.
Let us know what you find.
