The Shield Arms DS-20 is a high-capacity 20-round magazine built for Glock 17 pistols and compatible Gen 3 clones, designed to feed reliably when you need it most. Unlike standard-capacity alternatives, the DS-20 maintains a flush fit with your Glock 17-size frame—no uncomfortable extension protruding from your grip—while giving you the extra rounds serious shooters demand for competition, training, or duty use. If you run a Glock 9mm and want legitimate capacity without sacrificing ergonomics or shootability, this is a straightforward upgrade.
Shield Arms engineered the DS-20 for durability and dependable feeding. The magazine body is heat-treated to Rockwell hardness 45–50 and finished in a black nitrocarburize coating that resists corrosion and wear. The design incorporates custom high-impact nylon components and over-insertion tabs to protect your magazine and firearm during handling. It's built to the kind of standard that makes sense for a dedicated handgun owner who doesn't compromise on reliability.
If you're running a Shield Arms magwell on your Glock, the DS-20 is engineered to work seamlessly with that platform—smooth seating and positive retention. Whether you're at the range running drills, competing in practical pistol sports, or just want a robust spare magazine that holds real capacity, the DS-20 delivers the performance and fitment that justify the investment.
