Construction and fit
Polymer construction delivers impact resistance and corrosion immunity without the weight penalty of steel. The feed lips and follower geometry on the MASTERPIECE ARMS DEFENDER are engineered to work with MasterPiece Arms magazines and barrels, ensuring consistent alignment of 5.7×28 cartridges into the chamber. For operators who carry spare mags, the lightweight profile reduces fatigue during extended carry.
Capacity and tactical considerations
10- vs 20-round options
The 10-round magazine fits users in restricted jurisdictions or those who prefer a compact grip profile, while the 20-round option provides extended on-target time between reloads. Both capacities follow the same internal design, so training transitions between them are seamless.
Why 5.7×28 matters
The 5.7×28 cartridge excels with low recoil, flat trajectory, and high velocity from short barrels—benefits for personal defense and close-quarters applications. Using magazines built for that cartridge ensures consistent feeding of its small-diameter projectiles, reducing tip-over and stovepipe risks common with ill-fitting mags.
Masterpiece Arms, Inc. has a pedigree in designing platforms and accessories that are optimized as a system; choosing a magazine produced to match their pistols and rifles minimizes compatibility guesswork.
