The M30 Luftwaffe Drilling was a German triple-barrel hunting rifle developed in 1930 for Luftwaffe pilots as a survival weapon. The M30 incorporates two 12-gauge shotgun barrels over a rifle barrel chambered for the 9.3×74mmR round, a hunting cartridge equivalent to the modern .370 Nitro Express. The weapon was produced until 1942, and was primarily issued to Luftwaffe crews participating in the North African campaign.
— In-game description
The Drilling is unlocked for the Support kit at class rank 13. It is fairly unique amongst the shotguns, as the player can use the select fire function to switch between the two shotgun barrels and the single rifle barrel. The two systems have individual ammo pools, and are reloaded independently of one another by using the fire selector. Firing 12 Gauge Buckshot, the shotgun portion of the weapon has both the highest fire rate and ranged damage potential in its category, as well as the lowest capacity at two rounds. This means that although kills are achieved more consistently at medium distance, with a second follow-up shot available almost immediately if necessary, reloads are inexorably frequent - the reloading process is also the longest in class. The requirement is that players are generally limited to confrontational engagements against one or two enemies.
While the weapon's specialization tree prevents the use of Slugs, the selectable rifle barrel grants users of the M30 a significant advantage at long range over other shotguns. With velocity and performance similar to a bolt-action rifle round, the rifle is capable of a one shot headshot kill out to medium distance. Use of this mode is countered by its lengthy reload time between each shot, and as such is of limited effectiveness when not aiming for the head, as it is at least a two body shot kill against uninjured opponents.
In terms of other specializations, the left side path increases the performance of buckshot by reducing its ranged damage drop off and giving projectiles penetration damage, which can be especially helpful for the M30 Drilling when faced with more than two enemies who are lining up with one another. Alternatively, the right side boosts general handling characteristics for the mobility orientated play accentuated by shotguns.Quick Reload is a notable omission from the tree, and as such one of the largest deficiencies of the weapon cannot be mitigated.
