Well unless you have Oathkeepers on Hunter (an exotic piece of armor that gives you much faster draw time and let’s you hold your shot indefinitely), I you’ll suffer quite a bit against the current pulse rifle meta (unless your someone like iFrostbolt who is a god at PvP)
The game is currently being dominated by a handful of weapons.
Bygones (Gambit random drop; an absolute beast in all game modes)
Go Figure (4 burst pulse rifle that is very strong and sporting very good stats)
Luna’s Howl (3 tap handcannon that, when used properly, is nearly unstoppable in PVP)
Not Forgotten (a variation for Luna’s Howl with better range, both of them are extremely hard to get for the average PVP player)
Trust (Gambit handcannon with great stats and is great with pretty much any perk rolls)
Dust Rock Blues (has the best range for a shotgun in the entire game)
Mindbender’s Ambition (very strong PVP shotgun found by doing a hard mission and RNG)
Retold Tale (Random drop shotgun found in Forsaken’s endgame world)
Play of the Game (Most famous grenade launcher besides the Edge Transit, which is also good, and infamous for its ridiculous random drop rates).
Telesto (a fusion rifle (a gun that fires a burst of high powered lasers) that has a delayed explosion and is always a one shot when 4 at least of your lasers hit)
WHISPER OF THE WORM (THE strongest heavy weapon in the game; capable of EXTREME levels of damage and is the reward for an extremely hard mission)
One Thousand Voices (very powerful gun that fires a beam of delayed explosions and melts most bosses like butter; probably the rarest gun in the game right now, as it is the reward for an extremely hard raid, currently completed by like 8% of the world, I would like to say. On top of that, there is a hugely small chance of getting the gun at the end of the raid, because it is essentially a lottery game)
Ikelos Shotgun (VERY STRONG shotgun; highest DPS of all shotguns in the game. This is a must (or HIGHLY recommended) for most PVE activities. Found by defeating Escalation Protocol Boss on certain weeks)
Sleeper Simulant (This is still, I would say, the king of gambit (a hybrid PVPVE mode, very fun), or at least until more than like 5% of the playerbase has One Thousand Voices. It is capable of eliminating any player with one body shot in Gambit and also deals very high damage to bosses. Essentially a mix between a fusion rifle and sniper rifle (otherwise known as linear fusion rifle)
Other Notable Weapons (weapons I have come across that I enjoyed using):
Sunshot (powerful hand cannon that causes explosions on kills; capable of causing huge chain reactions of solar explosions)
Graviton Lance (previously the strongest exotic in the whole game. Just like sunshot, kills cause large detonations. Base damage is also very impressive)
Riskrunner (SMG that has the ability to never run out of ammo and provides defensive bonuses to the user when the user takes arc damage. This thing turns in to a murder machine under certain situations)
This is all that comes to mind right now.
If you get Forsaken, I would highly recommend getting some friends and hunting for some of the rarer weapons on this list.
