Considerations & Trade-offs
- Compatible only with the Ruger-57 pistol, so it is not a general-purpose 5.7x28mm magazine.
- The 20-round capacity may be more than some users want for a lighter or more compact carry setup.
- Black oxide finish is functional, but it may show wear over time with regular handling and use.
- As a factory steel magazine, it adds durability but may be less lightweight than polymer alternatives.
