The 1887 is a lever-action shotgun with a seven-shell tube that you can extend to ten. It deals solid close-range damage but works the action slowly, so it rewards careful shots over panic fire.
It is a close-quarters gun for clearing rooms and stopping rushing enemies. The lever action means a pause between shots, so step back or use cover between pumps. It is not built for anything past a few metres.
It takes standard, armor-piercing, soft-target, poison, blast and incendiary shells. Incendiary shells make up for the slow fire rate by leaving enemies burning. Add a laser pointer to tighten hip-fire, and a reflex or red dot sight if you aim down sights a lot.
The SPAS-12 and KSG cycle faster and suit sustained room fights better. The 1887 Sawed-off trades accuracy for a quicker 150 rounds per minute. Pick the full-length 1887 if you like its damage and the slower, deliberate rhythm.
1887 Sawed-off
The 1887 Sawed-off is a cut-down lever-action shotgun built for hip-fire at point-blank range. FND Vanguards, Engineers and Special Forces Snipers carry it, and Rodolfo Claudia's insurgency rewards its unique Bases Loaded version.
KSG
The KSG is a semi-automatic shotgun with a 15-shell capacity, so you can keep firing in a close fight. Buy it from Juan's arms dealers, or get its unique Excavation Execution from The Long Drop treasure hunt.
M133
The M133 is a pump-action shotgun that can drop most unarmored or lightly armored soldiers in one close shot. El Rubi is its unique version, built by a Yaran furniture maker.
RMS-18
The RMS-18 is a rank 4 shotgun with a 12-shell magazine, so you can keep firing longer than with most shotguns. You can buy it or loot it from FND chests.
