40mm grenade, incendiary
The 40mm incendiary grenade deals 25% less blast damage up front (but the same amount of impact damage from the grenade itself) and has a 40% smaller blast radius (7.03 yards or 6.43 meters) than the normal 40mm, but it also causes enemies to burst into flames, dealing 6 damage every second over a 15 second period.

40mm grenade, plasma
A sub-type added with the add-on Gun Runners' Arsenal. They have a slightly smaller blast radius. This does not result in any AP reduction from Plasma Spaz.

40mm grenade, pulse
A sub-type added with the add-on Gun Runners' Arsenal. They deal 8 points of damage to targets and have a 50% smaller blast radius, but deal an extra 150 damage to robots and 60 damage to power armor.
