The glove does have the advantages of being a small one handed infiltration weapon. Also no morale cost to fire, 0-G, plasma armor shred, and pretty good CQC rating at 140%. Also reasonably early in the tech tree at Ye magic shoppe.
Downsides: not that accurate, hit or miss usage since it arrives before voodoo school. Slightly anemic in power without voodoo boosting outfits.
It's a reasonable good sidearm for those with the psi power but primary weapon it is not. Maybe useful as a voodoo skill trainer since it calls V power and throwing for accuracy, unlike the wands which call firing for accuracy and voodoo skill as part of the damage.
