Considerations & Trade-offs
- The MOS setup adds optic flexibility, but it also means the pistol is oriented toward users who plan to run a red dot rather than a simple iron-sight-only setup.
- The 13+1 capacity and .45 ACP chambering reflect a larger, heavier-duty platform, which may be less convenient for those prioritizing a lighter carry option.
- Fixed Glock sights are included, so users wanting a different sight picture or a fully customized optic setup may need to plan for additional accessories.
- The flared mag-well and front slide serrations are practical handling features, but they are most relevant to shooters who value faster reloads and slide manipulation over a simpler, more minimal configuration.
