I like a suppressed sniper rifle for distant targets
Hunting Shotgun or Automatic Rifle for close to medium range
Lucky or the Police Pistol for close range and restricted areas.
I do wish Josh throw in unique revolver that magically fire buckshot, air-bust missile/grenade launcher, energy weapon with ricochet projectile etc
Sounds like Judge Dredd's Lawgiver...though that's a semi-auto. It carries multiple ammo types that can be switched between by voice commands. You got incendiaries, explosive rounds, ricochet rounds, AP and even homing rounds. And if anyone but you tries to use it the thing blows up in thier face.
