GRA中新增的这种电浆发射器被史密提进行了多种令人咋舌的改造，使其几乎能够连续不断地发射电浆团。干净的外壳and darker green in color, with additional hardware on the side and one large yellow vacuum tube replacing two of the tubes on the front-right side.較短的枪管, thick orange tape around the shaft以及造型独特的电浆稳定叶片使其看上去很有个性。
Although there are unique sounds for the weapon present in the files of Gun Runner's Arsenal, the weapon makes use of the Tesla cannon firing sounds instead.
This weapon is fully automatic, unlike other plasma casters. This causes the weapon to degrade almost as fast as the Gatling laser.
While The Smitty Special has a higher rate of fire than an un-modded plasma caster, with the HS electrode modification the two are roughly identical in DPS, making The Smitty Special a dubious improvement in real-time combat especially since the Smitty Special has a significantly lower critical rate and damage per shot making it much less effective against heavily armored targets. In V.A.T.S., however, The Smitty Special gets an edge over the plasma caster since, as an automatic weapon, it will get three shots (instead of two normally) for every one shot from the plasma caster.
By coincidence it is sold in the Silver Rush which is across the street from a pre-War store named Smitty's.
