What do the numbers mean on a grenade mod?

Question

In Borderlands what do the numbers on Grenade-Mods mean?

I don't think they mean the number of uses.
And I'm pretty sure the 45 grenade does way more damage than 45.

Answer 1

It is the damage but it doesn't necessarily mean that its going to hit for 45 points of damage. Keep in mind the damage that you do depends on the level of the person you are blowing up (in relation to your own level) and the chance for the grenade to "crit".

So throwing a grenade at a person of a lower level compared to you will do alot more than 45 damage.

Oh its worth mentioning if its a MIRV or "cluster" mod then you're going to see a heck of a lot more than just one big explosion.
