If you could carry any weapon...

[Bravo 21]

for a real weapon, id go with a crossbow, cause it has that kind of timeless apeal+plus, im less likely to kill myself with it,
for a fictional weapon, I would go with an self loading crossbow, with infinite ammuntion, and a bayonet.
yeah, i kinda like crossbows

 

[Shadow-Phoenix]

I would probably lug around a cryo beam gun or maybe even a chrono weapon to disable my enemies or zap them out of time.

 

[Prof. Monkeypox]

Hidden wrist blade.

 

[IronStorm9]

For non-realistic, I'll go with:

For realistic, a pair of these:

Can't go wrong with an energy scythe and two punching daggers.

 

[Master Kuja]

In terms of legality, wouldn't mind yomping around with a crossbow.

In terms of...Slightly less legal...I'll just post what I did in my last post.

 

[black-magic]

I have a giant hard-on for trench knives, as a boxer I love the idea of a punching/stabbing weapon.

 

[DocBalance]

For a plausible weapon, I'd want a cane-sword or a machete.

Less plausible, I'd want a bunch of lariats of different uses and sizes, preferably some non-lethal stunners, a few razor-wire, and some explosives.

 

[pwnzerstick]

The Painkiller.
Or Sasha, "It cost four hundred thousand dollars, to fire this weapon... for twelve seconds"

 

[Kitteh]

MPi-K. The East German copy of the AK-47. It has such a cool vibe. It was on the front lines of the german separation that was a cold war of tension.

 

[DSK-]

Either an Odachi or a Katana.

 

[Patrick Dare]

Shotgun (12gauge). Reliable, versatile. I know of no other weapon that is as interchangeable. Put in one kind of cartridge and you're set for combat, another for hunting fowl, another for hunting larger game, another for breeching doors, another for non-lethal combat. The only caveat is the short range.

If we're talking fantasy weapons I'll say the hammer of Thor just because I feel like it and I'm assuming wielding it would confer godly powers upon me.

Edit: On second thought the (I think this is what it was called) possible sword from The Scar by China Miéville.

 

[dark_mist34]

for real weapon Walther PPK

for fantasy Vash's gun from Trigun
or Alucard's twin large caliber handguns.

 

[Shadowsole]

A good strong Recurve bow, With poisons for the arrows
And a Sizable knife to fletch new arrows with,
I'm Not sure about the poison But the baw and arrows are legal,

Unplausible would be Flaming arrows that I Could reuse,

I'd keep fletches, nocks and extra string in my satchel

 

[Z of the Na'vi]

For a realistic weapon, I would have to go with a brick. You know, those things that they use to build walls and stuff? You can't go wrong when you are heaving a couple of those around.

Break some faces!

If I were to choose a more unrealistic weapon, I'd have to say the cannon that Tristana uses in League of Legends. It never runs out of ammo, fires continuously, has the capability of rocket-jumping, and looks oh-so badass.

She wants to shoot something!

 

[Steppin Razor]

Real - Desert Eagle
It's big, heavy and impractical for any form of distance shooting, but considering that I spend most of my time in the city where the chances of me needing to defend myself from someone that is any more than 20 feet way is relatively slim to non-existent, the old desert eagle would be eminently suitable. Not to mention that about half the time I probably wouldn't even have to fire it anyways as the mere sight of it would be enough to scare off most of the people looking to cause me trouble. You can know all its weaknesses and failings as a practical weapon, but I guarantee that if someone pointed one at you your reaction would consist of flight or shit yourself.

Decidedly less than real - Undecided

 

[Drakane]

An AR-15 built to my specs. (legal to open carry in my state, but I haven't EVER seen anyone openly carrying a rifle outside of hunting/shooting.)

my buddy has one w/ a grenade launcher attachment and licensed for explosives, as opposed to just teargas or w/e. Oddly he had to get the explosives license to get the non-lethal projectiles you shoot directly at ppl.

OT:
I've always been a fan of the duel wield. Double swords on my back using a single sheath allowing for one sword to be drawn upwords and the other down simultaneously. And probably double hand guns also, .40 cal

unrealistic, mini-gun on a tri-pod

pure fantasy... not sure... probably Lich Kings sword from WoW... come on ability to harvest souls for my undead army
