The SP-1/MP-1A Kit ships with both the SP-1 Sentinel Plate base and MP-1A interchangeable magazine post that will fit your Single Stack 1911.
The Sentinel Plate is the ideal platform to hold your magazine fed firearm for cleaning, repair, building, display, and storage. The Sentinel Plate is designed to assist everyone from the professional armorer to the recreational shooter with their firearms.
Our wide selection of interchangeable magazine posts attach your other magazine fed firearm firmly to the Sentinel Plate base. See our Magazine Post Selection page to choose the correct mag post for your gun.
One side of the Sentinel plate has a convenient pocket for holding parts, magazines, or cleaning supplies. The reverse side is flat for display or storage.
