Hyperion repeater pistols are very accurate but they have the feature of "reverse recoil": the longer the accuracy increases the longer the trigger is held. The listed accuracy on the weapon is what is achievable after the sustained fire increases their accuracy to maximum.
Due to its usage of the Vladof barrel, the Synergy has higher magazine size, higher rate of fire and reduced recoil but decreased accuracy compared to other Hyperion pistols. Thereby, the Synergy is a reliable pistol with medium-high-capacity magazine for quick killing at a distance from short to medium, especially in the hands of Zero.
In addition to the Synergy, a variant of this weapon exists in Borderlands: The Pre-Sequel as the Expeditious, made by the "old" Hyperion.
The Synergy is obtained randomly from any suitable loot source.
