That one weapon..

[Omikron009]

The AK-47 and variants thereof.

 

[Cpu46]

A reinforced shovel, or at least a weapon resembling one like the monks spade [link]http://en.wikipedia.org/wiki/Monk%27s_spade[/link]

 

[Eat Uranium]

Its got to be the Martini-Henry. No question.

 

[sansamour14]

i would have to say the G36 since i love that gun in any variation

 

[Hybridwolf]

Smith and Wesson M500. For when you have an elephant heading your way. Anything bigger:

Spoiler

I'm a firm beliver in overkill.

 

[CACAVILLE]

between the scar and the p90

 

[Redlin5_v1legacy]

I always liked the FG 42 from the early CoD games...

But my favourite weapon will forever and always be The Home Run Bat from Super Smash Bros!!

 

[Marter]

The Tojo Blades from Van Helsing. Those are so cool. I want them.

Or Wakka's Blitzball, just because of how much time I wasted on the Mini-game.

 

[Mr Montmorency]

SP12 with a longer barrel. Makes the supposed reduced damage effectively null when all the shots will hit you square in the face.

 

[Dango]

I have two
The first one being the reverse-blade sword wielded by a certain badass...

The badass known as Kenshin Himura/Battousai the Manslayer to be specific.
And also:
The wooden sword wielded by...

Taiga Aisaka

 

[Fatalistic]

Ashbringer, from WoW (Not Frostmourne, I'd rather not become the next Lich King...), or Gilgamesh from Devil may Cry 4.

I will go back into Martial Arts if I get that thing.

 

[SnowCold]

I will always Love Sasha...

VVVVZZZVZVZVZVZVZ OH-HAHAHAHA!

I'm guessing that you mean a chain saw?

Lol.

I hope you are kidding...

(Hint, look at my profile pic)

 

[SplattererRoss]

Frostmourne.
Nothing scares away a robber quite like a 29" blade

 

[kempoman14]

For me, it's a five-way tie in my heart for favorite weapon:

1. Silverballer. This is from the Hitman series (as if you didn't know that). Once you get this baby customized, dear god is it great.
2. Fiber Wire. Again, from the Hitman series. It's non-detectable by metal scanners, silent, and deadly.
3. AK47. The cheap, reliable icon. This is the bad-guy's gun... and I'm fine with that.
4. Long-bladed Stiletto. Hidden when needed, out when necessary.
5. Shovel. Oh hell yeah!

 

[Revolutionary]

STEYR 88.
Because it's the standard issue AR for my countries Defence force.

That's not helping.

[Iron_will]

The M-8 Avenger [http://masseffect.wikia.com/wiki/M-8_Avenger] from ME2, despite using the Vindicator a lot more. Only reason is because it just looks cool.

 

[MongodPenguin]

The BFG from the various Quake games :3

 

[Koeryn]

The Blue Rickenbacker 4001 usually wielded by one Haruko Haruhara...

Yeah that one...

Psh. Everyone knows the Gibson EB-0, 1961 model is where it's at.

Edit: Though on a slightly more serious note; the Barret .50cal Anti-Material. Somthing about being able to fuck up a guy's day, and the twelve guys behind him, and their car, from miles away just puts a bit of a smile on my face.

It's a toss up between the Gibson and the Barret .50cal, actualy. More in favor of the Gibson.

Allow me to introduce you to the Barret's bigger, angrier, brother: The Anzio 20mm.

Spoiler: The smaller gun is not a toy. Its a full sized Barret light-fifty.

Wait, not enough?

OT: After actually handling the FN-H SCAR-L, it's a wonderful gun, but damnit! I want a Tar 21! And I know where I can get them! Curse IWI for not finding an American Distributor and making me buy from Canada!

Spoiler

Looks so comfy.

 

[OceanRunner]

The M4 Assault Rifle. It's powerful and effective at just about any range.
