Need to increase walking speed while holding M9 TTT

Here is my code for the M9


if SERVER then
   AddCSLuaFile( "shared.lua" )
end
   
SWEP.HoldType			= "pistol"

if CLIENT then
   SWEP.PrintName			= "M9"			
   SWEP.Author				= "TTT"

   SWEP.Slot				= 1
   SWEP.SlotPos			= 1

   SWEP.Icon = "VGUI/ttt/icon_pistol"
end

SWEP.Base				= "weapon_tttbase"

SWEP.Spawnable = true
SWEP.AdminSpawnable = true

SWEP.Kind = WEAPON_PISTOL

SWEP.Primary.Ammo       = "Pistol"
SWEP.Primary.Recoil			= 1
SWEP.Primary.Damage = 10
SWEP.Primary.Delay = 0.35
SWEP.Primary.Cone = 0.02
SWEP.Primary.ClipSize = 7
SWEP.Primary.ClipMax = 80
SWEP.Primary.DefaultClip = 7
SWEP.Primary.Automatic = false

SWEP.HeadshotMultiplier = 15

SWEP.AutoSpawnable      = false
SWEP.AmmoEnt = "item_ammo_pistol_ttt"
SWEP.Primary.Sound = Sound( "Weapon_FiveSeven.Single" )
SWEP.ViewModel  = "models/weapons/beretta_M9.mdl"
SWEP.WorldModel = "models/weapons/w_pist_fiveseven.mdl"


I want to alter it to allow a player using it to run at a different speed (Default speed it 220 I want the player holding this to run at around 270)

Does anyone know how to go about this?

TTT overrides that, use the hook “TTTPlayerSpeed” or something like that. Check the ttt website

I’ve tried using that hook with no great success here http://forum.facepunch.com/showthread.php?t=1380125

I was hopping there would be some precedent with other weapons I could draw off of.

I’d like to make players run faster with certain melee weapons equipped so they would be able to overtake people for a backstab.
