It would be. What we were discussing is the picatinny mount for the mantis that mounts on the magazine floorplate.
It works great and doesn’t require a new holster for dry fire. But if you want to use the live fire features it would be a no-go, because the unit being attached to the magazine would be worthless after the first reload.
What I am trying to figure out is which weaponlight has the closest shape to the mantis x10, or what holster could accommodate my carry gun with a light that i could swap out for the mantis when training or doing competition and not have to buy 2-3 holsters. Hope that helps clarify the OP
