Editing weapon configs (Pistol)

This tutorial will briefly explain how to modify the pistols.

1. Open the weapon_pistol.txt in Disk:\Program Files\Steam\steamapps\common\Left 4 Dead 2\left4dead2\scripts with notepad

2. You'll see:

Here's an explanation on what some of these values do.
"MaxSpread" -> Decrease value to reduce the spread of the bullet over a distance.
"MinDuckingSpread" -> Accuracy when in crouching position (The lower the value the better. Same goes for the rest below.)
"MinStandingSpread" -> Accuracy when standing
"MinInAirSpread" -> Accuracy when in mid-air
"MaxMovementSpread" -> Accuracy while moving
"Damage" -> Increase value to cause instant kills to SI
"Range" -> How far the bullet will go
"Clip Size" -> Amount of bullets. By using a value of 100, having dual-pistols would mean having 200 bullets in total, the maximum you can have.
"VerticalPunch" - The amount of recoil the gun has, don't make this too high or else it may (literally) take you for a loop.
"SpreadPerShot" - The spread of the bullets/pellets shot by the gun.
"DeployDuration" - How long it takes to pull out the gun before shooting.
"DualDeployDuration" - Same thing, only for dualies. (Works only for pistols)
"addonattachment" - Can be "primary" (self explanitory), "pistol" (secondary weapon/melee slot), "medkit" (health slot), "pills" (Pills slot), or "molotov" (grenade slot).
"Tier" - Has to do with what other weapons the director spawns it with, can be 0, 1, or 2.
"MuzzleFlashScale" - How much muzzle flash.
"PenetrationNumLayers" - How many layers (of what, I'm not sure) the bullet can penetration.
"CycleTime" - Time it takes to refire the weapon, useful for Sub-Machine Guns.
"Bullets" - Bullets fired from each shot.
One final thing, where you have "Clip Size", there needs to be an underscore so it should be "clip_size".
