While technically a sporting blaster, the Penetrator's beam was focused in a double-nested set of galven circuits, letting it emit a powerful and highly focussed beam that matched the stopping power of heavier blaster pistols. This allowed the weapon to deliver massive punch per shot, while still retaining the accuracy of a sporting blaster - though as as side effect of the over focussing, this rendered it slightly less accurate than other typical sporting blaster pistols. The Penetrator's stun attack was less potent than that of many comparable weapons, and the weapons rate of fire was also slightly slower as well.
Designed to circumvent local governmental restrictions against citizens carrying military weapons, the weapon was considered to be a spies weapon of choice for it's power and accuracy, while not drawing attention to itself when inspected by authorities like many other heavier - but restricted - weapons.
Each Penetrator was marked with an identifier indicating production details.
