Power Shots use the long high-accuracy, high-damage barrel, typically having moderately sized magazines and fairly mediocre damage compared to other pistols with the same barrel. They make up for this with a very high reload speed. They can also burst fire when the trigger is held.
Like most Tediore weapons, a Power Shot is thrown forward when reloaded, with any rounds left in the magazine being lost but adding significantly to the damage from the explosion. The weapon will bounce a few times like a Lobbed grenade if it does not hit anything, but will explode instantly on contact with an enemy.
As with all pistols that use the Jakobs barrel, the Power Shot is only available at uncommon or higher rarities.
