The M1901 Mastiff Combat Shotgun is a Pilot anti-personnel energy semi-automatic shotgun manufactured by Lastimosa Armory that appears in Titanfall 2 and Apex Legends. It feeds from an underbarrel tube magazine.
The Mastiff can be considered easy to use, yet difficult to master. On one hand, it boasts several outstanding characteristics, such as low falloff, high range and damage, and (perhaps most uniquely), a completely flat spread.
On the other hand, it is not without its drawbacks - a slight, yet noticeable travel time, a low magazine size of four rounds, and a delay between shots to compensate for the high recoil. It's possible to miss shots even at close range by forgetting to take travel time into account.
When reloading from an empty mag, Pilots load in a single shell through the ejection port. This takes slightly longer than pushing shells through the loading gate, preventing players from loading in a single shell then firing while in emergency situations.
The M1901 Mastiff Combat Shotgun was developed specifically for low-gravity close-quarters engagements. the kinetic energy produced when fired in low-gravity can severely unbalance a Pilot with massive recoil, so the engineers at Lastimosa Armory incorporated a muzzle velocity dampening system which mitigates that energy and greatly reduces recoil.
Intended for low-zero gravity ship boarding and clearing operations, the Mastiff gained notoriety throughout The Frontier as a reliable and devastating combat shotgun. Shells can be fed through the under-mounted magazine or with the optional drum magazine upgrade. Troops from the 401st often refer to it as the "Mobile Claymore" as its high rate of fire proved to be devastating.
- As with all non-hitscan weapons, lead your targets! As mentioned before, it's possible to miss shots even at close range with the weapon.
- The Gravity Star pairs with this weapon nicely. It's capable of bending the trajectory of the Mastiff's projectiles, allowing you to get kills from behind cover. On a more mundane note, the Gravity Star will also negate most of the issues related to the Mastiff's travel time if an enemy is stuck.
- Avoid reloading from a completely empty magazine - the last round being loaded into the Mastiff's ejection port takes noticeably more time.
- The Mastiff's projectile bears heavy resemblance to the SA-3 Mozambique, indicating they operate on the same basis.

In Apex Legends, the Mastiff used to be one of the two original legendary weapons (Along with the Kraber), meaning it could not be found in the normal loot pool but instead could only be obtained through care packages, with a limited amount of ammo that was built into the weapon. This ammunition could not be dropped, and the ammunition for the weapon cannot be found anywhere on the map outside the weapon. The weapon itself came equipped with 4 starting shells, with 20 extra shells for reloading. It used ironsights and no optics. Once you used up all 24 shells, you had to throw the weapon away, as the ammunition was built in, meaning you could not find another mastiff and swap the ammo from that one into yours. This weapon remained legendary for 4 seasons, until season 5 when they decided to bring the mastiff into the loot pool and in turn bring the peacekeeper out and into the legendary category. As of now, you can use regular shotgun shells to load into the weapon and you can find the weapon anywhere on the map.
- After firing, two segments of the barrel appear to fold backwards. Given that the Mastiff fires a perfectly horizontal energy wave, we can only assume that it's to spread out the beam.
- The name of the weapon derives from the Mastiff dog breed.
- Technically it only holds three rounds rather than four - one is loaded directly into the breech of the shotgun through the ejection port. In firearms terminology, the Mastiff holds 3+1 rounds.
- The Mastiff's tubular magazine is hexagonally shaped, and if you inspect the shells in the loading animation, they have a hexagonal body.
- The Callsign Breacher can be unlocked via playing with the Mastiff. The Breacher XL callsign can be unlocked via advocate gift and Mastiff For Life can be bought in the Monarch's Reign pack.
