Including DLC there's 6 of them and they range from the early-to-mid game 9mm Pistol (Browning Hi-Power) and cowboy repeater (Winchester 1896) to the mid-game lever-action shotgun (winchester 1887) and late-game Brush Gun (winchester 1886), as well as the Automatic Rifle (BAR) from Dead Money and the .45 Auto Pistol (Colt 1911, obviously) from Honest Hearts. Between that and some of the uniques I can get in the campaign, I could feasibly do a full run throwing lead exclusively blessed by saint browning.
I don't actually wanna do DLC though, so I ought to see if there's a good way to change states to let me buy the auto rifle and .45 pistol from Gun Runners or some other rule to give me access to them.
I might also spec into some explosives and melee, at least let me use grenades and a knife or something.
