Are you asking what the best revolver is, or what the best looking revolver is?
The ranger sequoia is factually the best revolver/pistol. I don't think that can even be debated. If we are to include pistols my favourite though is the 12.7 pistol fully modded on my professional/sneak build. If not, then I would have to say "That Gun"
I just got all the DLC last week, and currently am playing an EW character, but can't wait to use lil' devil on my next playthough. Too bad cant mod it though
Okay I'm starting to get tired of all of these Ranger Sequoia is the best and that is undebatable comments. It actually is very debatable. The Ranger Sequoia a good gun, but Lucky is the best revolver classed sidearm:
-The Ranger Sequoia has much higher damage
-The Ranger Sequoia has much higher DPS
-The Ranger Sequoia has higher spread
-The Ranger Sequoia has higher crit damage
-Lucky has a much higher chance of getting a crit
-Lucky's ammo is much easier to find
-Lucky has nearly three times as much HP
-Lucky is much easier to get and can be gotten much earlier
-Lucky fires much quicker
-Lucky reloads much quicker
-Lucky uses nearly half the amount of AP in VATS
-Lucky has a magazine of 6 instead of 5
-Lucky has a Strength requirement of 3 instead of 6 and has a Guns requirement of 0 instead of 75
-Lucky weighs 2.5 lbs instead of 4 lbs
-Lucky is an improved holdout weapon
I like Lucky more, but the Ranger Sequoia is still a decent gun. A sidearm is something I use to shoot things when I'm caught off guard and need to draw quickly, something that's fairly easy to maintain and most importantly something that won't take up a lot of space. The Ranger Sequoia is a hand cannon, but I'd much rather use my 45-70 Govt. rounds for the Medicine Stick or Cass' Brush Gun. I myself am already carrying around a fully modded Hunting Rifle, I have no use for a mid to short range hand cannon.
