The MOS slide cuts support specific micro-optics, while the Slim Mounting Rail allows for accessory mounting when a setup calls for it. It also includes a reversible magazine catch, front serrations, and two 10-round magazines, giving it a practical feature set for users who want a compact pistol with optic-ready flexibility. Note that the MOS version does not include adapter plates, so optic setup will require the appropriate components.

Considerations & Trade-offs
- The MOS slide cuts are designed for specific micro-optics, but this model does not include adapter plates, so optic setup may require additional parts depending on the optic chosen.
- The included magazines are 10-round, which may be a practical limitation for users who prefer higher-capacity options where allowed.
- Its slimline, compact-size grip and short barrel length support concealability, but that also means it is built around a smaller carry profile rather than a full-size shooting platform.
- This item must ship to an FFL and is subject to shipping and magazine restrictions, so purchase and transfer logistics are more involved than with non-regulated accessories.
