I have absolutely not idea what you are talking about. Both Thorn and Bad JuJu [but Bad JuJu even more-so] are ATROCIOUS weapons. I'm not sure what your level of progression is, but at higher levels these weapons are unusable. Bad JuJu needs more damage and possibly a larger magazine size to be effective, and I don't even use hand cannons, but mostly everyone who I've talked to have dismissed Thorn as a viable option as a primary.
