Firearms build in pvp
At a glance I would say something like hgh pistols. Stacks of might can make any build viable. Take hgh, cleansing forumla and fast acting elixirs and in firearms pick up pistol related traits. Elixirs h and b and a kit, personally I prefer tool kit, and a third utility of choice. Maybe a flame turret to help protect points with smokescreens and cause high damage thanks to might stacked burns.You should have good offense and defense but it would vary depending on your amulet. I would start with celestial and go from there.

The typical Rifle/SD. Very squishy and has a hard time against elusive enemies (clone&stealthing mesmer, teleporting in and out thieves, stun warriors who can ignore CC for a long time, guardians who spam blocks) but deals a lot of burst damage.
You will find that it is the player, not the class, which kills you. Most of the above I have defeated where other times there was nothing much I could do.
Playing condition damage allows you to pick a Rabid amulet which cuts the squishyness in half but then I am unsure that Firearms supports traits for this. I will let others help since it is not my expertize.
