Gotcha. I tried finding examples of slugthrowers used against lightsabers, but I couldn't find any. The only thing I found was a vague reference about how some mercenaries had a repeater-slugthrower as a backup in case they ran into jedi, because the high-rate of fire was harder to deal with. 

At any rate, I don't have any issues with not being able to block slugs. Just figured we'd sort it out before I made my post so that Jaskan (who, without doubt, know that slugs can't be blocked effectively) didn't attempt such.

Makin' mah post naof.
