Boost capacity and cut reload time with GrabAGun’s Shotgun Magazines lineup—box mags and drums engineered for mag-fed pumps, semi-autos, and Saiga-style platforms. Rugged Mossberg 590M double-stack magazines feed 12-gauge buck or slugs without a hiccup, while Remington 870 DM mags keep America’s classic pump cycling fast in home-defense or 3-gun roles. Running a Saiga, SDS Lynx, or Panzer Arms AR-style scattergun? Detachable box magazines from SGM Tactical, ProMag, and AC-Unity lock in rock-solid with steel lugs and anti-tilt followers. Long range day ahead? Drop a 20- or 25-round 12-gauge drum and stay on the trigger longer between reloads.

Need lighter recoil or youth-friendly setups? Ten-round 20-gauge mags and handy five-round .410 options cover turkey blinds and range instruction alike. Bright shell-count windows, aggressive texturing, and reinforced feed lips deliver smooth, reliable cycling through mud, rain, or desert dust. Filter by gauge, capacity, or shotgun model to build the perfect mag stack, then add loaders, side-saddles, or sling-mounted caddies in one easy trip. Flat-rate shipping keeps checkout predictable, and Shoot Now Pay Later! financing lets you load up today and train harder tomorrow. When the action gets fast and every shell matters, shotgun shooters nationwide trust GrabAGun for magazines that feed flawlessly—shot after shot.
