There is more reason now than before. No way for people to cling to a weapon other than "they like it." A weapon like Hung Jury, which is a decent weapon, and other weapons like Hawksaw, a little on the OP side, are being used more often because the majority of players have to use the weapon that others define as best. And let's be honest, Firefly isn't that great of a perk. It has its uses, but not something that defines a gun. Hung Jury generally has decent stats even if the perks are meh, same with Hawksaw.
