MPL - magnetic port loader (for most pump)
On a empty start, you can gain advantage with the MPL by dropping the first shell on the lifter easily. Then work to close your action, top up your tube and get to shooting!
The MPL is universal to any shotgun and you can adjust the placement freely. Velcro patch included. See the dimensional drawing and order the optimized version to your shotgun.
The magnet force and shape of the MPL will allow you to place your shotgun also sideways or upright, if you need to start from a table or a stand. But the release towards the port will be smooth and easy.
