PROMAG DRUM TAU PT100 40SW 50RD BLK POLY

The ProMag 50-round drum magazine for Taurus PT100 .40 S&W gives you serious capacity without swapping mags at the range or in a competition setting. If you run a PT100 and want to maximize trigger time between reloads, this black polymer drum steps up dramatically from standard single-stack magazines. The engineering combines modern injection-molded polymer construction with traditional steel components where durability matters most — a practical blend that prioritizes reliability over unnecessary weight.

Built from a proprietary DuPont Zytel-based polymer body, the drum features a blue steel upper magazine tower and a heat-treated stainless steel spring. The injection-molded follower keeps rounds feeding smoothly through all 50 rounds. This isn't budget tooling; ProMag's manufacturing process — combining precision stamping, welding, and injection molding — is designed to handle consistent use. The whole package is made in the USA.

Whether you're running drills at your local range, testing your PT100's handling with extended capacity, or stocking up for a high-round-count training day, the 50-round capacity cuts down on administrative time. The black polymer finish is low-profile and won't stand out on a range bag or duty belt.
