Shotgun · 12 gauge

An automatic combat shotgun added with the Heists update — Saiga-12-style mag-fed with high sustained fire and brutal close-range damage. Unlocked via Heist completion.
The Shrewsbury Heavy Shotgun is a weapon featured in and as part of the Last Team Standing Update.
The weapon is mainly based on the Russian , a semi-automatic shotgun modeled after the Kalashnikov pattern. The variant seen in-game is a Saiga 12K, a modernized version equipped with a shorter barrel and a folding stock, which is used by law enforcement forces (by export) in the United States. The in-game model uses the same receiver as the Assault Rifle, despite the actual Saiga 12 having a different receiver from the Type 56.
In Grand Theft Auto Online, as part of the Further Adventures in Finance and Felony update, there is a unique Drum Magazine option that is similar to the one from the Assault Rifle, but incorporates rectangular patterns that give slight resemblance to ProMag Saiga drum magazines.
