Q & A
What optics footprint does the M400 ROSE use?
The slide is milled for the Shield RMSc footprint. This pattern also directly accepts optics like the Sig Sauer Romeo Zero and the Holosun HS407K/HS507K with their included adapter plates.
Is the M400 ROSE suitable for a first-time pistol owner?
It can be, given its manageable size and modern features. However, we strongly advise new shooters to seek professional training to develop safe handling skills and proficiency with any firearm, especially one intended for self-defense.
Does it come with a manual safety?
No, the M400 ROSE model we stock utilizes a trigger safety and internal safeties only. It does not have an external manual thumb safety lever.
