Sierra Defense T-1919 12GA 20-Round Magazine (Black)

Keep your T-1919 pattern shotgun running longer with the Sierra Defense 20-Round Drum Magazine. Built from high-strength, lightweight polymer that has been stress-tested to over 10,000 rounds, this OEM-pattern drum delivers consistent, reliable feeding in any condition. A corrosion-resistant steel feed tower and polymer anti-tilt follower work together to keep shells cycling smoothly, while a simplified internal design means fewer parts to clean and less that can go wrong. Whether you're running 3-gun stages, drilling for home defense, or putting rounds downrange at the range, this drum gives you 20 shots before your next reload. Fits TAR 12, TBP 12, and all major T-1919 pattern platforms.
