Thanks, CyberKN! If you've got the marks you might want to consider:

• 1000-Yard Stare (Vanguard Sniper) - Solar, Longview SLR10, Triple Tap, Perfect Balance, Mulligan
  
• The Smolder (Crucible Rocket) - Void, Aggressive Launch, Tripod, Flared Magwell, Grenades & Horseshoes
  
• Ruin Wake (Crucible Machine Gun) - Arc, Aggressive Ballistics, Life Support, Fitted Stock, Hidden Hand
  
• Hung Jury SR4 (Dead Orbit Scout) - Torch, Triple Tap, Hand-Laid Stock, Firefly
  
• Righteous VII (New Monarchy Auto Rifle) - Perfect Balance, Rifled Barrel, Glass Half Full
  
• The Vanity (Future War Cult Hand Cannon) - Luck in the Chamber, Extended Mag, Firefly

Not sure about the best shotgun (Patch-A?), pulse rifle (Villainy?) or Sidearm (Havoc Pigeon?).

I'm sure there are others - what are people filling their pockets with (until the new vault space opens)?

Don't Forget the Vertigo! (FWC)

Near-Max Blast Radius + Velocity + Grenades & Horseshoes

Thanks, CyberKN! If you've got the marks you might want to consider:

Pulse rifle (Villainy)

The Villainy is a must if you don't have the old Vendor Roll Nirwin's Mercy

Also check out the vanguard vendor Not Like the Others (scout rifle). Crowd Control, Explosive Rounds, Reactive Reload is a pretty solid combo.
