The Smitty Special is a heavily modified Winchester P94 which was first created by the legendary Smitty, the blacksmith of the Adytum, Boneyard in 2161, who was also the only one able to improve the Winchester P94 into a turbo version at that time, with a higher rate of fire.
This weapon is a GRA plasma caster with numerous modifications to increase performance. Most notably, it features a shorter barrel with larger, fan-shaped magnetic stabilizing claws on the end, and thick orange tape around the shaft. The body is also cleaner 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.
Mechanically, the Smitty Special is much more durable and has twice the ammo capacity of regular Plasma Casters, as well as a much higher rate of fire (seven shots per second as opposed to three), which balances out its lower damage output per shot and lower critical chance. It also has a much wider spread.
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.
