Hello there,

As per Wiki:

• Kuva Brakk: Higher rate of fire, magazine capacity, and shorter reload time
• These weapons have a max rank of 40. To obtain the maximum rank, the player must polarize the weapon five times, with each Forma increasing the maximum possible rank by 2 (similarly as the Paracesis).
• All Kuva weapons deal innate elemental damage in addition to physical damage. The amount of this damage is random, ranging from 25-60%, while the type of element is determined by the Progenitor Warframe, as per the table below:

According to the above, I added exactly 5 forma to this weapon, so we can obtain Mastery Points from it.

In this case, I recommend picking Magnetic as an elemental.

Some info about this sidearm shotgun:

• Very high Critical Chance
• The highest overall Status Chance of all secondary shotguns
• Very fast reload speed
• Innate 0.5 meter punch through
• Ammo efficient
• Has linear damage falloff from 100% to 4% from 10 m to 20 m target distance (distances are affected by projectile flight speed)
• Wide pellet spread cone makes the weapon ineffective beyond medium range
• High recoil

The [Steady Hands] mod on Exilus is here to reduce that high recoil by 60%.
