If activated, Pressurized Magazine will display an icon timer beside the player's health UI, and the Warframe will be briefly surrounded by a flashing energy ribbon.
The Fire Rate bonus is granted upon the end of the reload animation.
On event launch, Pressurized Magazine's duration was not only affected by rank, but also by the amount of Fusion energy in each rank.
Can be combined with Gunslinger, Lethal Torrent, Anemic Agility and Arcane Velocity for a total of +332% fire rate while aiming. This used on the Twin Grakatas will result in a fire rate of almost 173 rounds per second, making it possible to empty its entire 120-round magazine in 0.35 seconds.
If Pressurized Magazine is installed on the currently equipped pistol, reloading a primary weapon during a mission will display the flash effect associated with the mod's activation, though the weapon will not gain the fire rate bonus.
