If you're looking information on modifying Borderlands items:

The site is laid out in a simple format; just pick the page that corresponds to the weapon type you're looking for. Each part is listed by name, along with the type, the damage, accuracy and fire rate modifiers, and the extra effect it employs. Simple.

If you want to contribute:

Please follow the established format. If you are adding mags, detail the mag size in the extra effects column. The simplest way to help is as follows:

Pick a weapon type. The more of this type you have in your inventory, the easier this will be.

Have the first weapon with no parts (invisible gun). This will be your control weapon, as it has base stats.

Have the subsequent weapons have only one part. For instance, if you are testings barrels, have one with just barrel1, one with just barrel2, etc.

Make sure that your weapons have the same material and the same quality grade.

Calculate the percentage difference between the various stats to the control weapon. For instance, if control gun has 100 damage, and barrel1 gun has 125 damage, then barrel1 offers a +25% damage modifier. Round to the nearest 0.5%.
